ab94190 is a 293T cell transfected lysate in which Human HLA DP has been transiently over-expressed using a pCMV-HLS DP plasmid. The lysate is provided in 1X Sample Buffer. Note: For more details about how the transfected lysate was prepared view the preparation notes.
HLA-DPA1 belongs to the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DPA) and a beta (DPB) chain, both anchored in the membrane. It plays a vital role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (B lymphocytes, dendritic cells and macrophages). Within the DP molecule the alpha and beta chain contain the polymorphisms governing the peptide binding specificities, resulting in up to 4 different molecules.
