Rankem supplies Molecular Biology Reagents. Rankem is an ISO 9001:2000 and ISO 14001:2004 accredited company. The company supplies laboratory chemical requirements for Pharmaceutical Industries like High Performance Liquid Chromatography, Laboratory Reagent, and Analytical Reagent range, Dehydrated Culture Media, and Fine Chemicals and Custom Synthesis. The Molecular Biology Reagents experiments involve high level of complexity With long preparation periods and the high value of the samples. Therefore analysts cannot assume the risk of having contaminations due to the use of non-appropriate reagents. High value protein or nucleic acid preparations can be affected by an external and undetermined activity. Thus absence of enzymatic activity in molecular biology reagents is a necessity. Molecular Biology Reagents range has been tested for absence of Nucleases, Proteases, DNase, RNase wherever applicable.
