Background Information

Human major histocompatibility complex (MHC) antigens, also referred to as human leukocyte antigens (HLA), are encoded by genes located on the short arm of chromosome 6 (6p21.3). There are two classes of HLA antigens: class I (HLA-A, B and C) and class II (HLA-D). This class I molecules are polymorphic membrane glycoproteins composed of a heavy (alpha) chain (44 kDa) which is encoded by a HLA class I gene (HLA-A, B or C), and β2-microglobulin light (beta) chain (12 kDa). They are involved in the presentation of foreign antigens to the immune system. (PMID: 667938; 3375250)

I tried probing my WB for 1 hour at RT, but it looked terrible, so I will try an overnight incubation. I've also tried my IP twice, once using 4 ug/mL, and the second time using 10 ug/mL. I had no pulldown either time. I'm quite disappointed.

  • Applications: Western Blot, Immunoprecipitation,
  • Primary Antibody Dilution: 1:1000 for WB; 4-10 ug/mL IP
  • Cell Tissue Type: Ovarian cancer
