Interpolated concentrations of native Albumin in human serum and plasma samples.

The concentrations of Serum Albumin were measured in duplicates, interpolated from the Serum Albumin standard curves and corrected for sample dilution. Undiluted samples are as follows : serum 1 : 5 million, plasma (citrate) 1 : 5 million, plasma (heparin) 1 : 5 million, and plasma (EDTA) 1 : 10 million. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Serum Albumin concentration was determined to be 39.3 mg/mL in serum, 34.4 mg/mL in plasma (citrate), 30.8 mg/mL in plasma (heparin), and 34.5 mg/mL in plasma (EDTA).

製品の詳細

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.

補足情報

This supplementary information is collated from multiple sources and compiled automatically.

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.

Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs (Probable). Its main function is the regulation of the colloidal osmotic pressure of blood (Probable). Major zinc transporter in plasma, typically binds about 80% of all plasma zinc (PubMed : 19021548). Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli (PubMed : 6234017). Does not prevent iron uptake by the bacterial siderophore aerobactin (PubMed : 6234017).
