Summary This antibody recognizes the HLA-B7 antigen. Although highly specific, it can cross-react with HLA-B42 antigen.

Summary This antibody recognizes all polymorphic forms of chicken CD8 alpha.

Summary This antibody reacts with the high molecular weight form of the leucocyte common antigen (LCA) expressed by B lymphocytes and a subset of T lymphocytes.

Summary This antibody recognizes the HLA-B7 antigen and does not cross-react with HLA-B27 or other related antigens.It can be used to distinguish true HLA B27 positives from false HLA B27 positives (i.e. HLA B7 positive) in the investigation of diseases such as ankylosing spondylitis and anterior uveitis.

Summary This antibody recognizes an activation-dependent intracellular epitope of CD3 epsilon. Exposure of the epitope precedes CD3 phosphorylation and recruitment and activation of ZAP70, which initiates the signaling cascade produced by T-cell activation. APA1/1 provides the earliest known marker for TCR-mediated T cell activation.
