Macro & Micro-Test Sample Release Reagent

Short Description:

The kit is applicable to the pretreatment of sample to be tested, for facilitating the use of in vitro diagnostic reagents or instruments to test the analyte. The reagent is efficiently cleaved the sample under specific salt ion concentration and pH conditions, and then under the action of ionic surfactants, the protein is denatured and nucleic acid is released.
