Human leukocyte-derived interferon (HuIFN-alpha) can be displaced from controlled-pore glass (CPG) with alkylamines at 0.1-0.3 M concentration. The eluting power of an alkylamine correlates positively with the extent of its alkylation: CH3NH3 + less than (CH3)2NH2 + less than (CH3)3NH+ less than (CH3)4N+. Interferon can also be recovered using an electrolyte and ethylene glycol as cosolvents. Apparently, both hydrophobic and electrostatic forces are involved in the adsorption of HuIFN-alpha to CPG.
人白细胞衍生干扰素(HuIFN-α)在浓度为0.1 - 0.3 M时可被烷基胺从可控孔径玻璃(CPG)上置换下来。烷基胺的洗脱能力与其烷基化程度呈正相关:CH3NH3 + < (CH3)2NH2 + < (CH3)3NH+ < (CH3)4N+。干扰素也可用电解质和乙二醇作为共溶剂进行回收。显然,HuIFN-α吸附到CPG上涉及疏水作用力和静电力。
