  • RelevanceY. pestis has a number of virulence factors that enable it to survive in humans by facilitating use of host nutrients, causing damage to host cells, and subverting phagocytosis and other host defense mechanisms. Capsular F1 antigen is a main immunochemical component of Y. pestis surface. Its synthesis is determined by pFra plasmid and induced at 370C. F1 is aggregated on the outer membrane of the Y. pestis microbe as an olygomeric protein, forming a granular layer and gradually diffusing into the environment. Capsular polymer consists of multiple similar hydrophobic protein subunits, aggregating at physiological conditions. F1 subunit of the antigen is originally synthesized from 170 amino acids and has a molecular mass 17.6 K, then, after the elimination of the signal peptide during the secretion onto the surface, a protein with molecular mass 15.6 K and isoelectric point 4.1 is formed.

Thank you for contacting us.

Please find attached the CoC.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Unfortunately we have no information concerning this question, because we have not determined that in our laboratory.

This is a very new product, and I'm afriad all the information we have is on the datasheet. The anitbody has not yet been tested in Western Blotting. A standard protocol for WB is available in the "Protocols" section of the Abcam website
