Description

This mAb recognizes a protein of 36kDa, identified as ICOS-L, also called B7RP-1 or B7-related protein 1. It is a ligand for the ICOS receptor that initiates T and B cell proliferation and cytokine secretion. ICOS-L interactions play an essential role in T cell-dependent B cell activation in peripheral lymphoid organs such as spleen and lymph nodes. ICOS-L protein is present in myeloid leukocytes, and by Northern blot there are 2.4, 3.0, and 7.0 kb transcripts in brain, heart, kidney, and liver, with lower expression in colon and thymus, and a 1.1 kb transcript in leukocytes. Tumor necrosis factor alpha (TNF Alpha), granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) enhance its expression. LPS-induced up-regulation of ICOS-L is dependent on the MyD88-dependent signaling pathway.

Application Notes

Optimal dilution of the B7RP-1 antibody should be determined by the researcher.

Immunogen

A recombinant fragment of human ICOSLG/B7RP-1 protein (within amino acids 1-300) was used as the immunogen for the B7RP-1 antibody.

Storage

Aliquot the B7RP-1 antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
