Abstract

The histo-inhibitory factor (HIF) derived from homogenates of liver or kidney from hamsters infected with has been fractionated by column chromatography. It shows maximum absorption at 280 m, has a molecular weight of 142,000 and can be eluted from DEAE-cellulose or DEAE-Sephadex A—50 with 0.02 M phosphate — 4 M sodium chloride (1 : 1) HIF can be eluted from yeast cells at pH 10.0, thus a greater number of positive cultures from chronic histoplasmosis could be expected to result from pretreatment of clinical specimens in glycine buffer pH 10.0 prior to culture.

摘要

从感染了的仓鼠肝脏或肾脏匀浆中提取的组织抑制因子(HIF)已通过柱色谱法进行了分级分离。它在280 m处有最大吸收峰,分子量为142,000,可用0.02 M磷酸盐 - 4 M氯化钠(1:1)从DEAE - 纤维素或DEAE - 葡聚糖A - 50上洗脱下来。HIF在pH 10.0时可从酵母细胞中洗脱下来,因此预计在培养前将临床标本在pH 10.0的甘氨酸缓冲液中预处理,慢性组织胞浆菌病会产生更多阳性培养物。
