The CatchPoint SimpleStep ELISA employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. CatchPoint HRP Development Solution containing the Stoplight Red Substrate is added. During incubation, the substrate is catalyzed by HRP generating a fluorescent product. Signal is generated proportionally to the amount of bound analyte and the intensity is measured in a fluorescence plater reader at 530/570/590 nm Excitation/Cutoff/Emission.
Albumin (ALB), the main protein of plasma, has a good binding capacity for water, Ca2+, Na+, K+, fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. It also serves as a major zinc transporter in plasma, typically binding about 80% of all plasma zinc.

Albumin also known as ALB is a major plasma protein with a molecular mass of approximately 66.5 kDa. It predominantly gets synthesized in the liver and found abundantly in blood plasma. Albumin serves multiple functions including maintaining osmotic pressure and acting as a carrier protein for various endogenous substances like hormones fatty acids and bilirubin.
Biological function summary
Albumin plays a critical role in transporting small molecules like metabolites and drugs through the circulatory system. It is not a part of any complex but functions independently to bind transport and release various ligands. Albumin's affinity for hydrophobic molecules makes it essential for they to be solubilized in blood for proper metabolism and excretion.
Pathways
More than five binding sites on albumin facilitate its role in the fatty acid metabolism and renin-angiotensin system pathways. In fatty acid metabolism albumin interacts with transport proteins carrying fatty acids to tissues for energy production. Additionally during the renin-angiotensin system albumin modulates blood pressure through its interaction with angiotensin II which can influence vasoconstriction.
Researchers link albumin with nephrotic syndrome and liver cirrhosis. In nephrotic syndrome low levels of albumin (albumin low) can cause edema due to imbalanced osmotic pressure. In liver cirrhosis a reduction in albumin synthesis signifies liver damage. Albumin's interaction with proteins like angiotensin II correlates with complications such as hypertension further establishing the protein's role in health and disease contexts.
