[Preparation of a staphylococcal immunosorbent sensitized by antibodies to the M-subunit of LDH].

A simple and rapid immunochemical procedure is developed for estimation of the LDH1 activity which involved separation of LDH1 from other LDH isoenzymes using immunosorbent. The immunosorbent consisted of killed Staphylococcus aureus cells, membrane of which contained protein A with absorbed antibodies towards M-subunits of porcine LDH.
