the His6-AV-Ubiquitin-semapeptide expression in E.coli JM109DE3 expression host was found to be good and insoluble (inclusion body) ( Figure 4 & 5)

After the approved drug is on the market, whether generic or branded, API manufacturers must test each batch of the product according to the identified specifications using validated tests and, with each batch, issue a certificate of analysis (COA) that contains specific test results about the substance

The preparation method comprises: obtaining a compound having a structure represented as the formula I by taking a resin, activating the resin, and coupling L-glycine, L-arginine, L-glycine, L-arginine, L-valine, L- leucine, L-tryptophan, L-alanine, L-isoleucine, L-phenylalanine, and L-glutamic acid to the activated resin step by step so as to obtain a first peptide resin

The term "room temperature" as used herein refers to the temperatures of the thing close to or same as that of the space, e.g., the room or fume hood, in which the thing is located'
