How to prevent albumin masking of urokinase from conditioned media
Posted 03 April 2013 - 04:44 AM
However, albumin is complicating things because he dominates in my conditioned media extracts and I am not getting any uPA bands on Western blot, and when I Amidoblack stain my PVDF membranes I can clearly see one big albumin band from 45-65 kDA.
I am cultivating cells prior to extracting conditioned media, 6 hrs in serum-free media. Should I increase that time to get rid of albumin or do you know any other way how to prevent albumin interfering with my urokinase identification. Much obliged
