The solubility of granulopoiesis inhibiting factor (GIF) in various aqueous and organic solvents was investigated. GIF is soluble in water, 10% acetic acid, and 10% pyridine. It is not extractable by 1-butanol at low and high pH. A high solubility was found in polar organic solvents (ethanol-acetone 9:1, and chloroform-methanol 1:1), whereas GIF seems to be insoluble in pure chloroform.
对粒细胞生成抑制因子（GIF）在各种水性和有机溶剂中的溶解度进行了研究。GIF可溶于水、10%的乙酸和10%的吡啶。在低pH和高pH条件下，它均不能被正丁醇萃取。在极性有机溶剂（乙醇 - 丙酮9:1和氯仿 - 甲醇1:1）中发现其具有高溶解度，而GIF似乎不溶于纯氯仿。
