Fibroblast Growth Factor-basic (FGF-basic), also known as FGF-2, is a pleiotropic cytokine and one of the prototypic members of the heparin-binding FGF family. Like other FGF family members, bFGF has the ß trefoil structure. In vivo, bFGF is produced by a variety of cells, including cardiomycotes,...

GloMelt™ dye undergoes fluorescence enhancement upon binding to hydrophobic regions of denatured proteins. GloMelt™ can therefore be used to detect protein unfolding or protein thermal stability by performing a thermal shift assay, also called differential scanning fluorimetry or Thermofluor assay....

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

IFN-gamma Receptor II, also known as IFNGR2 and IFNGT1, is a transmembrane protein belonging to the type II cytokine receptor family. IFNGR2 is a non-ligand-binding beta chain of the IFN-gamma receptor. It is an integral part of the IFN-gamma signaling transduction pathway and is likely to interact...

PD-L1 and PD-L2 are ligands for PD-1, a costimulatory molecule that plays an inhibitory role in regulating T cell activation in the periphery. PD-L2 also known as PD-L2, B7-DC serves as a negative and a positive regulator of T cell function. The expression and function of PD-L2 are similar to PD-L1....

PACAP (1-38), a novel neuropeptide isolated from the bovine hypothalamus is more active than vasoactive intestinal peptide (VIP) in stimulating adenylate cyclase (EC50=7 nM). PACAP 1-38 (10 -9 M) increased substance P (SP), gastrin releasing peptide (GRP), and VIP release. PACAP 1-38 (10 -8 M)...
