The most common product of protein oxidation in biological samples are the carbonyl derivatives of proline, arginine, lysine and threonine residues. Such derivatives are chemically stable and found universally across all proteins.
Many oxidative stress markers degrade over time, but Protein carbonyl content can still be measured reliably even in samples frozen for up to 1-2 years.
Our OxiSelect™ Protein Carbonyl Assays allow fast, reliable measurement of protein damage. A variety of formats is available including Western blot, fluorometric, spectrophotometric, and the most popular ELISA kit. More information
TECH CORNER: Testing Samples for Oxidative Stress
Q: I want to test my samples for oxidative stress, but there are so many different oxidative stress assay kits. How do I know which kits to use?

Advanced Glycation End Product (AGE) Assays
AGE modification of proteins can contributeto the pathophysiology of aging and long-term complications of diabetes, atherosclerosis and renal failure.
Our range of AGE assays include an AGE ELISA Kit to broadly detect the formation of advanced glycation end products, as well as ELISA kits to detect specific AGE species:
The presence of nitric oxide, via the intermediate reactive molecule peroxynitrite, most often results in nitration of tyrosine residues (i.e. formation of 3-Nitrotyrosine) in proteins. The 3-Nitrotyrosine marker is extremely stable and easily measured in cell lysates, plasma, or serum.
Our Nitrotyrosine Assay Kits are available in two formats: Western blot and a 96-well competitive ELISA.
It is with great pride and immense pleasure that we introduce the Creative Bioarray QualiStem® Alkaline Phosphatase Live Staining Kit which provides a fast, simple and sensitive method for AP detection without fixing the cells. The reagent is nontoxic to the cells and the fluorescent signal will be discharged from the cells by exocytosis completely within two hours after removal of the staining solution, allowing the cell to be used for follow-up studies
Since the Monkeypox was first detected on 7 May 2022 in the United Kingdom, more and more cases have been confirmed in non-endemic countries, Creative Biogene decided to do our share for supporting the scientific community against this disease and would like to introduce our Monkeypox Virus Real Time PCR Kit.
