Target
-
RelevanceTCR (T cell antigen receptor) recognizes foreign antigens and translates such recognition events into intracellular signals that elicit a change in the cell from a dormant to an activated state. TCR is a heterodimer composed of either alpha and beta or gamma and delta chains. CD3 chains and the CD4 or CD8 coreceptors are also required for efficient signal transduction through the TCR.

Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 16 kDa
Observed band size: 21 kDa why is the actual band size different from the predicted?
Additional bands at: 56 kDa, 74 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 90 seconds
TCR alpha contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
