FAQs for HUWE1 Antibody

Showing  1 - 1 of 1 FAQ Showing All
  • Q: Can you tell me what percentage of gel was used for the Western Blot and what the transfer time and conditions were for product NB100-652.

    A: This product is tested by a collaborator so I do not have the specifics for this antibody in particular at the moment. I have consulted our lab and for a large protein like this (around 480kDa) we recommend either a 5% or 3-8% gradient polyacrylamide gel. Additionally, we recommend that you boil your samples for 10 minutes at 68 degrees and use your standard transfer conditions. If you need a ladder for that high of a molecular weight, we use HiMark from Invitrogen.
