The Human ALB (Albumin) ELISA quantitates ALB in serum and plasma.
原理方法
The Human Albumin (ALB) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of Albumin (ALB) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
The sandwich complex is formed by the addition of a second (HRP-linked) detection antibody specific to Albumin (ALB). Excess reagents are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody-target complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution. The intensity of the signal, measured spectrophotometrically at 450 ± 2 nm, is directly proportional to the concentration of Albumin (ALB) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Albumin is a soluble, monomeric protein with a molecular weight of approximately 65-67 kDa that comprises about one-half of the blood serum protein. Human serum albumin (HAS) is the most abundant protein in human blood plasma, and has a serum half-life of approximately 20 days. Albumin functions primarily as a carrier protein for steroids, fatty acids, and thyroid hormones and plays a role in stabilizing extracellular fluid volume. Albumin is a globular, unglycosylated serum protein synthesized in the liver as pre-pro-albumin which has an N-terminal peptide that is removed before the nascent protein is released from the rough `produce the secreted albumin. Serum albumin has a good binding capacity for water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. The main function of albumin is the regulation of the colloidal osmotic pressure of blood.
