Texas Redâ€šÃ Ã¶âˆšÃ†â€šÃ Ã¶â€šÃ Ã¨â‰ˆÃÂ¬Â© labeled deglycosylated Avidin D is further purified to obtain a cell sorter grade reagent using unique labeling methods we can incorporate more fluorochrome into a protein without affecting the binding properties of the protein. An improved conjugation technique coupled with a purification step to reduce nonspecific binding resulting in the high Fluorophore ratio, increases the efficiency of cell sorting. This product can also be used in fluorescent microscopy when higher sensitivity and lower background is essential. The sensitivity of the signal can be further improved by using the amplification procedure withBiotinylated Anti-Avidin D antibodies. Avidin D-Texas Redâ€šÃ Ã¶âˆšÃ†â€šÃ Ã¶â€šÃ Ã¨â‰ˆÃÂ¬Â© excites at about 595 nm and has an emission maximum at about 615 nm.
