HYBRID-DNA-MOLEKYL, TRANSFORMERAD MIKROORGANISM OCH SETT ATT FRAMSTELLA PROTEIN A

摘要

A recombinant DNA molecule comprising at least one deoxynucleotide sequence coding for protein A or an active polypeptide fragment thereof and a process for preparing such a recombinant DNA molecule by introducing a deoxynucleotide sequence coding for protein A or an active fragment thereof into a cloning vehicle. Also a microorganism transformed by such a recombinant DNA molecule and its preparation are provided as well as a process for preparing protein A by culturing such a transformed microorganism in a suitable nutrient medium and isolating the product.
