Hi doctor,

I just now had a 3 to 4 seconds exposure to UV radiation when using agarose gel electrophoresis. Also, yesterday when preparing to run DNA, a small amount of Ethidium bromide landed on my finger. I immediately washed it with water. What is the possibility that these may cause a skin mutation or cancer?



Welcome to icliniq.com.

  • You did the right thing washing the exposed area of your skin. You should not worry as the exposure time is very short and exposure was only to a small amount of Ethidium bromide.
  • I doubt you will have blisters or redness or itching.
  • You have to be very careful while using these chemicals. You should wear double gloves and wash your hand carefully after removing gloves even if gloves were not torn.
