PRODUCT INTRODUCTION

description

Citric acid monohydrate is an organic compound. Due to its chelating effect and ability to stabilize nucleic acids, citric acid is used to prepare sodium citrate buffer for solutions like SSC. As a molecular biology grade reagent, it has been confirmed to be free of DNase and RNase activities.
