Relevance: Receptor for the attractant L-serine and related amino acids. Is also responsible for chotaxis away from a wide range of repellents, including leucine, indole, and weak acids.Chotactic-signal transducers respond to changes in the concentration of attractants and repellents in the environment, transduce a signal from the outside to the inside of the cell, and facilitate sensory adaptation through the variation of the level of methylation. Attractants increase the level of methylation while repellents decrease the level of methylation, the methyl groups are added by the methyltransferase CheR and roved by the methylesterase CheB.

Purity: Greater than 90% as determined by SDS-PAGE.
Storage Buffer: Tris-based buffer,50% glycerol
Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
