CD8 is a cell surface glycoprotein found on most cytotoxic T lymphocytes and is used as a marker for these cells. It acts as a coreceptor for T cell receptor and functions to recognize MHC –I antigens. 10%-30% human lymphocytes are CD8 positive. Human CD8 Magnetic Beads are used for isolation or...

Interleukin-1 Beta (IL-1 Beta) is a proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1 alpha and IL-1 beta bind to the same receptor and have similar if not identical biological properties. These...

Single donor specimens collected from donors prior to and continuing through disease progression.

5-(and-6)-Carboxyrhodamine 110-X (full name: 5-(and-6)-Carboxyrhodamine 110-X, hydrochloride) is similar to 5-(and-6)-carboxyrhodamine 110. The X linker molecule is useful to reduce the interaction between the dye and the molecule to be labeled.       ...

Exendin-4 is a novel 39-amino acid peptide isolated from the venom of the Gila monster Heloderma suspectum. It shares 53% sequence homology with GLP-17-36amide and interacts with the same membrane receptor. Exendin-4 enhances glucose-dependent insulin secretion, suppresses inappropriately elevated...

Interleukin-4 Receptor , also known as IL-4RA and CD124, is a transmembrane glycoprotein belonging to the class I receptor family. It is highly expressed by activated T-cells. IL-4RA couples with ? chain to form the type I receptor for IL-4. The extracellular domain of IL-4RA binds to IL-4 and...
