Transient overexpression cell lysate was tested with Anti-HLA-DPB1 antibody (H00003115-M01) by Western Blots. SDS-PAGE Gel
HLA-DPB1 transfected lysate Western Blot
Lane 1: HLA-DPB1 transfected lysate ( 29 KDa). Lane 2: Non-transfected lysate.
Use it directly for immuno-precipitation, or heat lysate with SDS gel loading buffer to 95°C for 5 minutes followed by rapid cooling for western blot application. If dissociating conditions are required, add reducing agent prior to heating.
In modified RIPA Lysis Buffer.
Store at -80°C. Aliquot to avoid repeated freezing and thawing.
HLA-DPB belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DPA) and a beta chain (DPB), both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and its gene contains 6 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and exon 5 encodes the cytoplasmic tail. Within the DP molecule both the alpha chain and the beta chain contain the polymorphisms specifying the peptide binding specificities, resulting in up to 4 different molecules. [provided by RefSeq
