1. What is the Immunosuppressant Treatment?

    An immunosuppressant is any substance that performs immunosuppression of the immunedescribe the image system. They may be either exogenous, as immunosuppressive drugs, or endogenous, as, e. g., testosterone. When the immune system function is suppressed, there is an increased susceptibility to infectious diseases and cancers.
  2. Kainic Acid: An Excitatory Amino Acid Receptor Agonist Selective for Kainate Receptor Subtype

    OVERVIEW Kainic Acid is a marine product, derived from the red marine alga Digenea Simplex. Kainic Acid is an excitatory amino acid receptor agonist selective for kainate receptor subtype; conformationally restricted analog of L-glutamic acid. Kainic acid is a potent central nervous system stimulant, and has been developed as the prototype neuroexcitatory amino acid for the induction of seizures in experimental animals, at a typical dose of 10-30 mg/kg in mice. Kainic acid is neuroexcitotoxic and epileptogenic, acting through specific kainate receptors.
  3. A23187: A Carboxylic Acid Antibiotic Which Simultaneously Uncouples Oxidative Phosphorylation and Inhibits ATPase

    OVERVIEW A23187 is a carboxylic acid antibiotic which simultaneously uncouples oxidative phosphorylation and inhibits ATPase of rat liver mitochondria incubated in a magnesium-free medium. The antibiotic acts as a freely mobile carrier to transport calcium and magnesium, but not potassium, from an aqueous medium buffered at pH 7.4 into a bulk organic phase. A23187 causes a progressive release of endogenous magnesium and...
  4. Calyculin A: Potent Tumor Promoter Used in Mouse Skin Experiment

    Calyculin A, a marine toxin isolated from Disodermia calyx, is a structurally distinct inhibitor of PP1 (protein phosphatase 1) and protein phosphatase 2A (PP2). It has been shown that Calyculin A displays inhibitory properties towards the endogenous phosphatase of smooth muscle myosin B and induces contraction in the muscle fibers.
  5. Cantharidin: Used in Cancer Treatments and Inhibits PP1 & PP2A

    Cantharidin was first isolated in 1810 by Pierre Robiquet, a French chemist then living in Paris, from Lytta vesicatoria. Secreted by many species of blister beetle, most notably by the 'Spanish fly' (Lytta vesicatoria), cantharidin inhibits protein phosphatases 1 and 2A (PP1, PP2A).
  6. Cancer Research Using Blasticidin S

    Blasticidin S is an antibiotic used by scientists in bio-research to select cells modified by genetic engineering. It inhibits the growth of a wide range of prokaryotic and eukaryotic cells by interfering with protein synthesis. Blasticidin S allows the selection and maintenance of cells expressing the blasticidin-resistance gene.
  7. Why should it be A.G. Scientific’s HRV3C Protease?

    Human rhinovirus 3C protease (HRV 3C Protease) is a cysteine protease that recognizes the cleavage site of Leu-Glu-Val-Leu-Phe-Gln-Gly-Pro, commonly referred to as the PreScission Site. It cleaves between Gln and Gly. The recombinant form of the HRV3C protease is a restriction grade protease that has robust activity at 4°C and high specific activity and great stability. It does not require...
