Abstract

We have developed three electrophoretic methods for analytical and preparative separation of native and heat-denatured beta-lactoglobulin. The methods can be applied, e.g., to optimize dairy milk processing, especially in laboratories which are not provided with expensive column chromatographic instruments. The methods consist of native PAGE followed by electroelution. Consequently, the eluted proteins are in solution in a biologically active and native form, and can therefore be used immediately for further analyses.

分离天然和热变性牛β -乳球蛋白的电泳方法。
我们开发了三种电泳方法用于天然和热变性β -乳球蛋白的分析和制备分离。这些方法可以应用,例如,优化牛奶加工,特别是在没有昂贵的柱层析仪器的实验室。方法包括天然PAGE电泳和电洗脱。因此,洗脱的蛋白质在溶液中具有生物活性和天然形式,因此可以立即用于进一步分析。
