Analysis Affinity and Kinetics of Prostate Specific Antigen (PSA) with Antibody M612166 by KinExA (CAT#: STEM-MB-0060-CJ)

Introduction

Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The blood level of PSA is often elevated in people with prostate cancer, and the PSA test was originally approved+E71 in 1986 to monitor the progression of prostate cancer in men who had already been diagnosed with the disease. PSA testing (along with a DRE) is also often used by health care providers for individuals who report prostate symptoms to help determine the nature of the problem. In addition to prostate cancer, several benign (not cancerous) conditions can cause a person’s PSA level to rise, particularly prostatitis (inflammation of the prostate) and benign prostatic hyperplasia (BPH) (enlargement of the prostate). M612166 is the 100% PSA Monoclonal Antibody.




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; 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.
