titlePurpose

Knowing whether or not our HEK293 cells express Syk will better enable us to determine what level of Syk expression we need in our HEK293 model system and how much cross-talk we can expect from recruitment of endogenous Syk to the BCR upon antigen binding.

Gels:

We have the any kD gels in the lab (expire 2015) and this will work for both our western blot and antibody group's western blot.

If we run out of the above gel we are considering getting the 4-25% gel in order to optimize our resolution. This will also work for both our western blot and antibody group's western blot.

 

The gels currently in the lab have 10 lanes.  Here is the plan for the gel:
