I think I have this one right.
Western Blot kits are either store bought or produced internally. These difference seem to lead to preferential expression of bands ostensibly related to variable degrees of antigenic expression.
Clongen and Labcorp (using the same kit) express more 23 bands.
Stony Brook expresses more 93 bands
IgeneX expresses more 30,31 bands.
Perhaps they are all correct.
I have found this helpful in my efforts to reconcile the different reports.
