What Is Electroporation?

 Electroporation is the application of an electric current to a living surface (as the skin or a cell membrane) in order to open pores or channels through which something (as a drug or DNA) may pass. Electroporation or electropermeabilization is usually used in molecular biology as a way of introducing some substance into a cell, such as loading it with a molecular probe, a drug that can change a cell’s function, or a piece of coding DNA.

In molecular biology, the electroporation process is commonly used for cell transfection/transformation, the non-viral DNA transfer, of bacteria, yeast, and plant protoplasts. Electroporation is also highly effective for the introduction of foreign genes in tissue culture cells, especially mammalian cells. 

In laboratory practice, electroporation is done with an appliance that creates an electromagnetic field in the cell solution known as an electroporator. The cell suspension is pipetted into a glass or plastic cuvette which has two aluminum electrodes on its sides. Electroporation is used in many areas of molecular biology research as well as in the medical field. Some applications of electroporation include, DNA transfection or transformation, direct transfer of plasmids between cells, induced cell fusion, trans-dermal drug delivery, cancer tumor electrochemotherapy and gene therapy.

Benefits of electroporation

  • It is non-viral, non-toxic and can be used on all cell types including mammalian, bacteria, algae, plant and yeast.
  • It can be used on cells in all forms, in vitro or in vivo/ex vivo.
  • In vitro is Latin for “within glass” and includes suspension cell, tissue slice/whole organ, and adherent cell.
  • In vivo/ex vivo Latin for “within the living”and includes tissue/whole organ, in ovo, and in utero.
  • It’s not limited by plasmid size and uptake is immediate and requires no incubation.
  • It’s reproducible, highly efficient and easy to use.

Electroporation Applications 

  • For gene/drug delivery, to study the effects of genes or drugs on cells.
  • For research, medical, farming and manufacturing process.
  • Vaccine Development
  • To stimulate a more robust immune response.
  • B-cell cloning, for monoclonal antibody production in mammalian cells
  • Bacterial Libraries

Whiteboard Wednesday: What You Should Do After Using PPE Supplies

Today on Whiteboard Wednesday we discuss proper ways to dispose your PPE (personal protection equipment) supplies after use. Properly disposing your PPE supplies in your medical facility is very important for reducing the spread of infection. Be sure to watch our Whiteboard Wednesday video below!

The Different Types of Ultrasound Scans

There are several different types of ultrasound scans depending on the part of the body being examined. There are external, internal and endoscopic ultrasound scans. An external ultrasound involves the use of a an ultrasonic sensor also known as a transducer or transceiver which is placed on the patients skin and is moved over the body part being examined. An ultrasound gel is applied to the skin to improve the movement of the transducer and ensure continuous contact between the skin and the transducer. 

The Different Types of Ultrasound Scans

There are several different types of ultrasound scans depending on the part of the body being examined. There are external, internal and endoscopic ultrasound scans. An external ultrasound involves the use of a an ultrasonic sensor also known as a transducer or transceiver which is placed on the patients skin and is moved over the body part being examined. An ultrasound gel is applied to the skin to improve the movement of the transducer and ensure continuous contact between the skin and the transducer. 

The transducer produces ultrasonic waves in pulses which pass through the skin into the body and are reflected back by various body parts. The reflected waves are detected by the transducer and are then converted by the computer which is connected to the transducer. The computer then produces a real-time image on the monitor and can also be recorded for further examination. External ultrasounds are used to examine the developing fetus  in the pregnant mother’s uterus, kidneys, heart, gallbladder, liver, and the reproductive organs.

Internal Ultrasound scans involve placing an ultrasound probe into the vagina (transvaginal) or rectum (transrectal). During a transvaginal ultrasound procedure, ultrasound waves are used to examine a woman’s reproductive organs, including the uterus, cervix, and vagina. The transrectal ultrasound procedure  (TRUS) or prostate sonogram is an ultrasound technique  that is used in the diagnosis of prostate conditions by sending sound waves through the wall of the rectum into the prostate gland and surrounding tissues.

The endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy (insertion of a probe into a hollow organ) is combined with ultrasound to obtain images of the internal organs in the chest and abdomen. Endoscopic ultrasonography is commonly used in the upper digestive and respiratory system. Another procedure is the transesophageal echocardiogram (TEE) which is an alternate way to perform an echocardiogram. During a transesophageal echocardiogram a specialized probe containing an ultrasound transducer is passed through the patient’s esophagus. Endoscopy procedures may be uncomfortable and as a result the patient may be given a sedative or painkiller prior to the procedure.

The FDA  has provided the following guidance for healthcare providers for internal or endoscopic ultrasound procedures, use sterile ultrasound gel for procedures with mucosal contact in which biopsy is not planned, but any possible added bioburden  would be undesirable, or in which mucosal trauma is likely, such as transesophageal echocardiography (TEE) procedures, transvaginal ultrasound procedures and transrectal ultrasound procedures without biopsy. In an FDA press release the following statement was made regarding the usage of ultrasound gel, “Be aware that once a container of sterile or non-sterile ultrasound gel is opened, it is no longer sterile and contamination during ongoing use is possible.”

The FDA is advising health-providers to remember that only unopened ultrasound gel labeled as sterile is safe to use for procedures that require sterile products. Those products that are not labeled with respect to sterility are not sterile, the agency emphasized. Refer to your facility’s infection control or other risk control procedures for more specific information.

Happy National Radiologic Technology Week!

This week (November 3-9, 2013) is National Radiologic Technology Week! This week was created to celebrate and honor the work of radiologic technologists. For 2013, the theme is “R.T.s: Positioning Ourselves for Excellence.”

Wilhelm Conrad Roentgen, Father Of Diagnostic Radiography

Wilhelm Conrad Roentgen, referred to as the father of diagnostic radiography, was a German physicist who first discovered the X-ray on Friday, November 8, 1895. Roentgen, a professor of physics at the University of Wurzburg (Germany), was working with cathode rays. Roentgen termed this new discovery “X-rays” or “invisible light”, using the mathematical designation for something unknown or “X”.

Happy National Radiologic Technology Week!

This week (November 3-9, 2013) is National Radiologic Technology Week! This week was created to celebrate and honor the work of radiologic technologists. For 2013, the theme is “R.T.s: Positioning Ourselves for Excellence.”

Radiology technologists are medical personnel who regularly perform diagnostic imaging exams and perform radiation therapy treatment. They often specialize in certain diagnostic imaging areas such as, bone densitometry, cardiovascular-interventional, CT, MRI, nuclear medicine, radiography, sonography, etc.

We would like to thank all the radiology technologists for their hard work all year round! Here is an inside look into a typical day of an x-ray technologist at the Connecticut Children’s Medical Center:

Why Wearing A Face Mask Is Important

Hospital and medical center staff wear face masks to prevent the spread of disease. This post will highlight why wearing a face mask is so important and how to wear a face mask in your medical setting.

Why wear a face mask?

Wearing a face mask will help prevent the spread of infection and prevent the individual from contracting any airborne infectious germs. When someone coughs, talks, sneezes they could release germs into the air that may infect others nearby. Face masks are part of an infection control strategy to eliminate cross-contamination.

How should your face mask be worn?

  1. Always wash your hands with soap and water before touching the face mask.
  2. Remove mask from the dispenser or box and make sure the masks do not have any holes or tears.
  3. Make sure you determine which side is the top and which is the front of the mask, so you can properly wear the mask.
  4. Face masks with ear loops: hold by the ear loops and put the loops around each ear.
  5. Face masks with ties: bring mask to your nose and place the ties over your head to secure with a tie.
  6. Face masks with bands: hold mask to your nose and pull the top strap over the crown of your head and pull the bottom strap over your head so its at the nape of your neck.
  7. Pull the mask over your mouth and chin

Our CoolOne Ear Loop Masks with Magic Arch Support are hypoallergenic and fluid resistant, ideal for medical settings. The magic arch support holds the mask away from the nose and mouth and provides a cooler, more comfortable breathing chamber without obstruction of downward vision.
