CD8 alpha Antibody (752-0085-82) in IHC (P)
Multiplex IHC on human FFPE normal lymph node and T-cell lymphoma tissues. HIER was performed on de-paraffinized sections using citraconic anhydride solution in a decloaking chamber at 120 degrees Celsius for 20 min. Following antigen retrieval, the sections were illuminated with white light in a buffer containing 24 mM NaOH and 4.5% H2O2 in PBS for 30 min, and then permeabilized with 0.1% Triton X-100/PBS ...

产品详细信息
Description: The monoclonal antibody C8/144B recognizes the human CD8a molecule, an approximately 32-34 kDa cell surface receptor expressed either as a heterodimer with the CD8 beta chain (CD8 alpha/beta) or as a homodimer (CD8 alpha/alpha). A majority of thymocytes and a subpopulation of mature T cells and NK cells express CD8a. CD8 binds to MHC class 1 and through its association with protein tyrosine kinase p56lck plays a role in T cell development and activation of mature T cells.
Applications Reported: This C8/144B antibody has been reported for use in immunohistochemical staining of formalin-fixed paraffin embedded tissue sections.
Applications Tested: This C8/144B antibody has been tested by immunohistochemistry on formalin-fixed paraffin embedded tissue using high pH antigen retrieval and can be used at 10 µg/mL. It is recommended that this antibody be carefully titrated for optimal performance in the assay of interest.
Using conjugate solutions: Centrifuge the protein conjugate solution briefly in a microcentrifuge before use; add only the supernatant to the experiment. This step will help eliminate any protein aggregates that may have formed during storage, thereby reducing nonspecific background staining.
靶标信息
Cluster of differentiation 8 (CD8), a type I transmembrane glycoprotein of the immunoglobulin family of receptors, plays an integral role in signal transduction, and T cell differentiation and activation. CD8 is predominantly expressed on T cells as a disulfide-linked heterodimer of CD8alpha and CD8beta, where it functions as a co-receptor, along with T cell receptor (TCR), for major histocompatibilty complex class I (MHC-I) molecules; whereas its counterpart, CD4, acts as a co-receptor for MHC-II molecules. CD8 exists on the cell surface, where the CD8alpha chain is essential for binding to MHC-I. CD8 is also expressed on a subset of T cells, NK cells, monocytes and dendritic cells as disulfide-linked homodimers of CD8alpha. Ligation of MHC-I/peptide complexes presented by antigen-presenting cells (APCs), triggers the recruitment of lymphocyte-specific protein tyrosine kinase (Lck), which leads to lymphokine production, motility and cytotoxic T lymphocyte (CTL) activation. Once activated, CTLs play a crucial role in the clearance of pathogens and tumor cells. Differentiation of naive CD8+ T cells into CTLs is strongly enhanced by IL-2, IL-12 and TGF-beta1.
