How can I get around the fact that the H1R GPCR multimer upon lysate preparation gets denatured and aggregates on the SDS PAGE gel?

I am working with histamine receptor 1, a G protein couple receptor (GPCR), and when i prep my lysate for SDS page gel run I heat them up at 95C/3 min. I am getting protein aggregation in my...

Has anyone come across S-myc tag rather than the conventional c-myc protein tag? Can we detect this protein tag using anti-c-myc antibodies or not?

Has anyone come across using S-myc tag rather than the conventional c-myc protein tag? I received a construct that had S-myc and I am not sure if this is the same tag as c-myc. There is no...

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....
