Human Albumin TRF-PINCER Assay Kit, 96-well format


Clear selection


This assay is ideal for quick screening and quantification of human albumin in urine, saliva, culture media, plasma, and serum samples.

Human serum albumin (HSA), 67 kDa, is a non-glycosylated, negatively charged plasma protein synthesized primarily in the liver. Albumin comprises approximately one-half of the blood serum protein. Serum albumin is important in regulating blood volume by maintaining oncotic pressure. It effectively buffers plasma pH. Albumin also serves as a carrier of hydrophobic molecules, including lipid soluble hormones, bilirubin, bile, calcium, and iron. Several low- and high-affinity ligand binding sites on HSA are responsible for the binding of most pharmaceutical drugs. Clinically, serum albumin measurements are used as a diagnostic screen for several disease conditions. Low serum levels are associated with liver damage/cirrhosis of liver, nephritic syndrome, inflammation and malnutrition. High albumin levels usually reflect dehydration.


Product Applications:

  1. Determine protein concentration of biological samples

  2. High-throughput screening of fusion proteins used in drug delivery

  3. Biomarker of kidney or liver damage, malnutrition, dehydration


The protocol for the TRF-PINCER® Assay is simple and fast.
