PCNA antibodies are useful biomarkers in DNA repair studies. PCNA is one of several proteins essential for the completion of nucleotide excision repair, a multi-stage process involving 20 - 30 proteins, and an important factor in repairing damage and mutations to the DNA helical structure.

We at Novus Biologicals have over 230 products in our antibody catalog devoted to nucleotide excision repair. NER is a multi-stage sequential process involving over 30 proteins, all of which have been widely studied. Being the primary method to repair DNA damage caused by agents ranging from UV radiation to chemotherapy drugs, our NER antibody database is widely used by cancer research groups.

The mammalian DNA repair process encompasses a large number of protein pathways, and forms an important part of our antibody catalog. The past 30 years have seen tremendous advances in the understanding of these mechanisms, with Wood, et al. recently compiling an updated inventory of at least 150 human DNA-repair proteins. This added considerably to the scope of the antibody database of us at Novus Biologicals.

We at Novus Biologicals are constantly updating our antibody catalog in order to provide as comprehensive a database as possible for molecular biology researchers. Not all our antibodies are derived from proteins found in mammalian or human tissue. Some are derived from single-celled or non-eucaryotic organisms which produce harmful effects when introduced to humans or animals.
