Abstract

A screening assay for phospholipase C using a chromogenic substrate incorporated into agar medium is described. The assay directly visualizes phospholipase C activity of mycoplasma lysates and membranes on agar plates, or the activity may be measured by spectrophotometry. The results from the assay confirm the presence in Ureaplasma urealyticum of phospholipase C, which is predominantly localized in the membrane fraction. The procedure has the potential to screen phospholipase C activity in other mycoplasmas and microorganisms in general.

摘要

描述了一种使用掺入琼脂培养基中的显色底物对磷脂酶C进行的筛选测定法。该测定法可直接在琼脂平板上观察支原体裂解物和膜的磷脂酶C活性,或者通过分光光度法测量该活性。该测定结果证实解脲脲原体中存在磷脂酶C,其主要定位于膜组分中。该方法有可能用于一般筛选其他支原体和微生物中的磷脂酶C活性。
