  • Cayman’s Protein Carbonyl Colorimetric Assay is a colorimetric assay for the measurement of oxidized proteins. The carbonyls of protein samples are derivatized using 2,4-dinitrophenylhydrazine. Formation of a Schiff base produces the corresponding hydrazone which can be analyzed…

  • D-Lactate Assay Kit

    Cayman Chemical

    D(−)-Lactate is a stereoisomer of lactate and is present in blood at only 1-5% the concentration of L(+)-lactate. Exogenous sources of D-lactate include fermented foods such as yogurt, sauerkraut, and pickles. D-lactate is normally produced in the gastrointestinal tract, mainly by…

  • This nuclear receptor assay system utilizes proprietary non-human cells engineered to provide constitutive, high-level expression of the human peroxisome proliferator-activated receptor gamma (NR1C3), a ligand-dependent transcription factor commonly referred to as PPARG or PPARγ.…

  • Hemoglobin (Hb or Hgb) is a globular protein found primarily in erythrocytes that carries oxygen from the lungs to tissue where it releases oxygen and then returns carbon dioxide (CO2) from the tissue to the lungs. Hemoglobin also binds CO2, carbon monoxide (CO), and nitric oxide (NO).…

  • PAD2 is a guanidino-modifying enzyme that catalyzes the conversion of specific arginine residues to citrulline in a calcium-dependent manner. This enzyme has been implicated in several diseases, including rheumatoid arthritis (RA), retinal degeneration, and certain cancers. PAD2 has been shown to…

  • PAF-AH catalyzes the hydrolysis of the potent biologically-active phospholipid PAF, generating inactive lyso-PAF. Cayman’s PAF-AH assay kit provides an accurate and convenient method for measurement of PAF-AH activity. The assay uses 2-thio PAF which serves as a substrate for PAF-AH. Upon…

  • Cayman’s Autophagy/Cytotoxicity Dual Staining provides a convenient tool for studying the regulation of autophagy and cytotoxicity at the cellular level. The kit employs MDC, an autofluorescent substance incorporated into multilamellar bodies by both an ion trapping mechanism and the…
