Product details:
Human Prealbumin ELISA Kit ab231920 is a rapid single-wash 90-min sandwich ELISA kit to measure Human Prealbumin in Serum, Heparin Plasma, Citrate plasma, EDTA Plasma, Cerebral Spinal Fluid, Cell culture supernatant, and Milk. This Simplestep sensitivity is 6.3 pg/mL.
How the assay works
Human Prealbumin 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
Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.

Prealbumin also known as transthyretin is a protein with a molecular mass of approximately 55 kDa. The liver primarily synthesizes prealbumin and it is present in the bloodstream. Functionally prealbumin transports thyroxine and retinol-binding protein-retinol complex facilitating the distribution of these molecules to target tissues. As such it plays an integral role in maintaining retinol and thyroid hormone homeostasis.
Biological function summary
Prealbumin interacts with retinol-binding protein to form a complex essential for vitamin A transportation. This complex prevents renal filtration of retinol-binding protein thereby conserving vitamin A in circulation. The protein's role extends beyond transport as it influences neurophysiological processes due to its ability to bind thyroid hormones and affect gene expression related to metabolism. Prealbumin is primarily a part of the thyroxine-transferring complex reinforcing its critical position in hormonal and vitamin dynamics.
Pathways
Prealbumin's role in the thyroxine-binding globulin pathway highlights its importance in the endocrine system. Another pathway where prealbumin contributes significantly is the vitamin A metabolic pathway. In these pathways prealbumin maintains functional relationships with proteins like retinol-binding protein and thyroxine-binding globulin which jointly modulate thyroid hormone transport and vitamin A dynamics across cellular membranes.
Prealbumin directly associates with familial amyloid polyneuropathy and malnutrition. Familial amyloid polyneuropathy involves the deposition of prealbumin-derived amyloid fibrils in peripheral nerves impacting neuron function. In malnutrition decreased prealbumin levels serve as a biomarker reflecting poor nutritional status. Clinically prealbumin's relation to retinol-binding protein and thyroid hormone levels facilitates its use in diagnosing and monitoring these conditions.
