Test Principale: This assay employs a two-site sandwich ELISA to quantitate TTPA in samples. An antibody specific for TTPA has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTTPA present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TTPA is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TTPA bound in the initial step. The color development is stopped and the intensity of the color is measured.

Product Overview: TTPa encodes a soluble protein that binds alpha-trocopherol, a form of vitamin E, with high selectivity and affinity. This protein plays an important role in regulating vitamin E levels in the body by transporting vitamin E between membrane vesicles and facilitating the secretion of vitamin E from hepatocytes to circulating lipoproteins. Mutations in this gene cause hereditary vitamin E deficiency (ataxia with vitamin E deficiency, AVED) and retinitis pigmentosa. Using rat alpha-Ttp to screen a liver cDNA library, followed by PCR, Arita et al. (1995) cloned full-length human alpha-TTP. The deduced 278-amino acid protein has a calculated molecular mass of 31.7 kD and shares 94% identity with rat alpha-Ttp. Northern blot analysis of several human tissues detected a 4.5-kb alpha-TTP transcript in liver only.

Stability: The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C) .
