[Isolation and immunochemical properties of LDG-5 from swine muscle].

: Homogeneous crystalline isoenzyme LDH5 was isolated from pig muscles with a yield of 33%. Antiserum, developed to the purified LDH5 preparation from pig muscles, reacted with human and pig LDH isoenzymes containing M subunits and did not interact with LDH1 isoenzyme. The heterologous antiserum might be used for estimation of LDH1 content in human blood serum.
