Purification is conducted from broken yeast cells by following scheme: clarification, ammonium sulfate precipitation, ultrafiltration, cation exchange chromatography, zonal centrifugation, size-exclusion chromatography, sterile filtration.
20 mM KH2PO4 (pH 7.2), 500 mM NaCl, 1.7 mM EDTA, 0.01% Tween-80, 1 mM 2-Mercaptoethanol.
Purity > 90 % (SDS-PAGE).
Each lot is tested for protein content (Lowry method), lipid content (Total lipid), purity (SDS-PAGE), carbohydrate content (Anthrone method), antigen content (Immunoblot).
Tested in quantitative immunoblot with anti-HPVL1 antibodies.
-20 °C (-15 … -30 °C allowed)
