MIDLAND is primarily engaged in the custom manufacture and sale of synthetic DNA and RNA products. MIDLAND'S experience in custom oligonucleotide synthesis is unsurpassed in the biotechnology industry. For over 20 years, MIDLAND's products have been used by researchers worldwide.
The focus of the MIDLAND business plan is to be able to make a single oligonucleotide when a unique molecule is needed and then to be able to make hundreds or thousands of similar oligos as the successful project passes from a research idea to full-scale production.

We Specialize in Highly Modified Oligos!
