Bacterial Spore Germinants and Cogerminants — compiles free amino acids such as arginine, asparagine, alanine, valine, and threonine that act as trigger molecules (germinants) or cogerminants in the germination of bacterial spores. These compounds interact with germinant receptors on the spore to initiate the transition from the dormant phase to a vegetative cell.
This group of amino acids is used by microbiology researchers in studies of bacterial spore germination mechanisms, including Bacillus and Clostridium, by observing spore responses to single germinants as well as mixtures. Certain amino acid combinations, such as alanine with asparagine, are often used as a standard trigger cocktail in germination assays in endospore research.
Example products in this collection: TCI A0526 74-79-3 L-(+)-Arginine, TCI C0388 50-22-6 Corticosterone, TCI A0542 5794-13-8 L-Asparagine Monohydrate, TCI C1317 53-06-5 Cortisone, TCI A0179 56-41-7 L-Alanine, TCI D6119 64-85-7 21-Hydroxyprogesterone, TCI V0014 72-18-4 L-Valine, TCI H0149 71-00-1 L-Histidine.
Pay attention to the L or D stereochemical configuration because germinant receptors are enantiomer-specific, as well as the hydrate or anhydrous form, which affects solubility in the test solution. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
