Major Histocompatibility Class II molecules are primarily expressed on B-cells and antigen presenting cells (APCs). They are composed of two polypeptide chains. These polypeptides (alpha and beta) are about 230 and 240 amino acids long, respectively, and are glycosylated. These polypeptides fold into two separate domains; the non-polymorphic alpha chain and the polymorphic beta chain. The antigen binding region of the molecule is bounded by a beta-pleated sheet on the bottom and two alpha helices on the sides, and is capable of binding (via non-covalent interactions) a small peptide of about 10 amino acids. -

Immunocytochemistry/ Immunofluorescence analysis of Raji (human Burkitt's lymphoma B lymphocyte) cells labeling MHC Class II beta using ab170867. The cells were fixed with 4% paraformaldehyde then permeabilized with 0.1% Triton X-100. The cells were then incubated with ab170867 at 1:50 dilution followed by a further incubation with ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed at 1:1000 dilution (shown in green). Nuclear DNA was labelled in blue with DAPI. Cells were counterstained using ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) at 1:200 dilution (shown in red). Secondary antibody only control: PBS instead of the primary antibody.

Lysates/proteins at 15 µg per lane.
Secondary
All lanes : Goat Anti-Rabbit IgG (HRP) with minimal cross-reactivity with human IgG at 1/2000 dilution
Predicted band size: 29 kDa
Observed band size: 25-35,50-65 kDa why is the actual band size different from the predicted?
Exposure time: 40 secondsBlocking and diluting buffer and concentration: 5% NFDM/TBST.
The molecular weights observed are consistent with what have been described in the literatures representing MHC Class II beta monomer (25-35kDa) and dimer (50-65kDa) (PMID: 15322189, 17174123)
