TP-ⅠM,A polymer of Tachyplesin Ⅰ

Description

A long-chain protein formed by polymerizing four identical short TP-I monomer peptides.

Usage and Biology

After the tp1 polymer is expressed, it is inactive. It will be expressed as a long-chain protein by the engineered bacteria and taken to the extracellular environment by the signal peptide and then hydrolyzed into four active short peptides.

By externally synthesizing an expression vector with Tachyplesin I multimers, transferring the vector into BL21 for antibiotic screening to obtain a single clone, culture it in liquid medium to OD600 and add IPTG to induce 12 hours to obtain recombinant protein, and collect After ultrafiltration and concentration, purified Tachyplesin I polymer was obtained. SDS-PAGE electrophoresis identification showed that the target protein had been obtained.
