Recognition by Electrophoretic Localisation of the Extracellular Products of Selected Strains of Staphylococci

SUMMARY Extracellular products of 13 selected strains of staphylococci were separated and detected by the electrophoretic localisation technique. Seven haemolysins were recognised, and were designated α, αl, cationic β, anionic β, δ, δ1 and ∊. These migrated respectively c. 18, 18, 36 and 30 mm towards the cathode and 0, 10, and 14 mm towards the anode. Two lipases migrating 3 and 18 mm towards the anode, one gelatinase migrating 36 mm towards the anode, two nucleases migrating 20 and 32 mm towards the anode and one phosphatase remaining at the origin were also recognised.
