Abstract

A hybrid DNA molecule is disclosed by this invention capable of cellular expression comprising the DNA sequence for protein G. Said DNA sequence has substantially the same IgC binding properties as naturally occurring protein G. The molecule may be comprised of DNA sequences coding for fragments of protein G. Moreover, said DNA sequence may code for both fragments of protein G and protein G. The DNA sequence can be isolated from streptococcal DNA.
