Quality standard of recombinant prothymosin alpha and function in aquatic feed

Abstract

Prothymosin alpha (ProTα) is a special protein without tertiary institutions. In this study, we focus on the stability of ProTα obtained from Chinese human genes which is slightly different from other reported ProTα genes. Quality standard, isoelectric point, mass spectra and bacterial endotoxins were tested to confirm the properties of the protein. We applied ProTα to the aquatic feed of Penaeus vannamei to observe its effects on water quality and shrimp immune function. The results showed that the protein can reduce the nitrite produced during the breeding process and can enhance the immunity of Penaeus vannamei.
