适用范围:1.1 This test method covers an analytical test for determining the amount of total aqueous extractable protein associated with natural rubber (NR) and its products. Water soluble proteins are extracted in a buffer solution and then precipitated to concentrate them and also to separate them from water soluble substances that may interfere with the determination. The extracted protein is redissolved and quantified colorimetrically by the modified Lowry method using a protein standard.
