Analysis Affinity of 504B3 for LPA species by KinExA (CAT#: STEM-MB-0035-CJ)

Name: Analysis Affinity of 504B3 for LPA species by KinExA
SKU: STEM-MB-0035-CJ
Rating: 5 (1 reviews)

Introduction

Lysophosphatidic acid (LPA) is a bioactive lysophospholipid that acts through its six cognate G protein-coupled receptors. LPA signaling is involved in many physiological processes such as cell proliferation, chemotaxis, and smooth muscle contraction, as well as cell surviva. Recent studies suggest that LPA may play an important role in the pathophysiology of cancer and may be used as a biomarker for ovarian cancer. Lysophosphatidic acid antibody (504B3) was originally developed and patented by Lpath Therapeutics.

Principle

KinExA is a two-stage analysis system. In the first stage, a number of solutions are prepared, where one partner remains constant (constant binding partner, or CBP) and the other (titrant) is variable, usually serially diluted. As the titrant is added, the free CBP decreases and is analysed by a sophisticated and precise microfluorescence measurement device. The signal generated can be mathematically related to the affinity (KD) of the two molecules for each other, as well as the kinetic parameters of binding (kon) and dissociation (koff).

Applications

Oncology & Cancer; Immunology/Inflammation, Toxicology; Pharmacology

Procedure

1. preparation of the functionalized beads which will capture the analyte for measuremen.
2. preparation of a series of solutions consisting of a constant initial concentration of one component of the binary reaction and serial dilutions of the other reactant. The component that is kept constant is the constant binding partner (CBP) , and is the one which will be analyzed.
3. each reaction mixture is sampled and the fluorescence of free CBP bound to the capture beads is obtained for subsequent numerical analysis.
