Description

QuickStep Human ALB (Albumin) ELISA Kit

The QuickStep Human ALB (Albumin) ELISA Kit is a specialized assay designed for the quantitative measurement of Albumin levels in human biological samples. Albumin is a crucial serum protein synthesized by the liver with multifaceted roles in maintaining oncotic pressure, transporting biomolecules, and modulating immune responses. This ELISA kit provides researchers with a reliable tool for studying Albumin levels, offering insights into liver function, kidney health, and overall protein metabolism. Albumin is a key biomarker associated with various health conditions, including liver disease, renal disorders, and malnutrition, making it a valuable marker for clinical diagnostics and biomedical research.

The quantification of Albumin levels using this ELISA kit enables precise analysis of its concentration in biological samples, facilitating investigations into disease mechanisms and therapeutic interventions. The QuickStep Human ALB ELISA Kit is characterized by exceptional sensitivity and specificity, ensuring accurate and reproducible results. Manufactured under stringent quality standards, this kit offers robust performance and ease of use, making it an excellent choice for research studies focused on Albumin biology, clinical diagnostics, and disease biomarker discovery.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human ALB. Samples (or Standards) and biotinylated detection antibody specific for Human ALB are added to the micro ELISA plate wells. Human ALB would combine with the specific antibody. Then Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human ALB, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 ± 2 nm. The OD value is proportional to the concentration of Human ALB. You can calculate the concentration of Human ALB in the samples by comparing the OD of the samples to the standard curve.

ALB is the most abundant protein in human plasma and serum. This protein is normally present in serum at concentrations ranging from 30 to 50 mg/mL and accounts for approximately 60% of the total protein content in serum [1]. ALB has a molecular weight of 66.7 kDa and is composed of a single polypeptide chain with 585 amino acids and 17 disulfide bonds. ALB is involved in many physiological processes. For instance, this protein aids in the regulation of osmotic pressure and pH in blood. In addition, ALB mediates lipid metabolism, sequesters toxins, and works as an antioxidant (i.e., it binds free radicals) [2]. Another important function of ALB is its action as a transport protein for a wide range of solutes that include some low mass hormones, fatty acids, and drugs
