Product details:
Human Albumin ELISA Kit ab227933 is a rapid single-wash 90-min ELISA kit to measure Human Albumin in urine, serum and plasma. This SimpleStep ELISA® sensitivity is 30 pg/mL.
How the assay works
Human Albumin SimpleStep ELISA® employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.
Assay Specificity
This kit recognizes both native and purified Human IgA protein in serum, plasma, milk, urine, saliva, and cell culture media samples only. Cell and tissue extracts have not been tested with this kit.

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.
