Purified F1 antigen of Y. pestis vaccine strain EB.
MaxLight(TM) 650 is a new Far-IR stable dye conjugate comparable to Alexa Fluor(TM)647, DyLight(TM)649, Cy5(TM) and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (655nm), Emission (676nm), Extinction Coefficient 250,000. Y. 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 17.6Kd, then, after the elimination of the signal peptide during the secretion onto the surface, a protein with molecular mass 15.6Kd and isoelectric point 4.1 is formed. Applications: Suitable for use in Immunohistochemistry and FLISA. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight(TM)650 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
