Molecular Research Center, Inc., founded in 1989 by P. Chomczynski, develops and manufactures innovative products for the isolation and analysis of RNA and DNA. It is a corporation " run by scientists for scientists" and we are continuously working on the development and improvement of molecular biology techniques.

Beginning with the single-step method for RNA isolation we have worked to simplify nucleic acid isolation protocols while providing improved recovery and sample purity. Our patented RNA and DNA extraction techniques are recognized around the world for their performance, reliability and cost effectiveness. 

Norgen Biotek Corp.  
Norgen has successfully exploited part of its IP to develop over 70 sample preparation kits for RNA, DNA, and protein purification for research purposes.

These kits include the leading kits in the world for the isolation and purification of total RNA and microRNA from various samples, as well as novel multi-analyte kits that allow for the sequential isolation of RNA, DNA and proteins from the same sample using a single column with no sample splitting.

Norgen also offers a full line of PCR reagents, buffers, molecular weight ladders and plastics/filtration devices.
