Comparative data

Streptavidin-AP vs competitors

Figure 1. A Streptavidin-Alkaline Phosphatase conjugate was purchased from a commercial supplier. The conjugate was compared to Streptavidin-Alkaline Phosphatase conjugate made with Innova Biosciences' Lightning-Link® conjugation technology in ELISA as shown. It can be seen that the Innova Biosciences' Streptavidin-Alkaline Phosphatase conjugate outperforms the competitor.

Additional information

Streptavidin is purified from the bacterium Streptomyces avidinii. It is a tetrameric protein that is composed of identical subunits, with the tetramer having a molecular weight of approximately 53kDa. Each subunit binds one biotin molecule with a very high degree of specificity and affinity. The Kd for this interaction is in the region of 10-15M.

Alkaline Phosphatase is a hydrolase enzyme. It is extracted from bovine intestine and purified using multiple precipitation, fractionation, chromatography, and filtration steps. Alkaline Phosphatase is frequently employed in immunoassays, and a commonly used colorimetric substrate for it is PNPP; the product of this reaction, p-nitrophenol, can be read at 405nm. Fluorogenic substrates such as 4-methylumbelliferyl phosphate (MUP) may also be used.
