产品描述:
Streptavidin is a 55 kDa (subunit MW 14 kDa) biotin-binding protein isolated from Streptomyces avidini. Streptavidin is superior to avidin, because it does not contain carbohydrate like avidin and has no net charge at neutral pH. Streptavidin~biotin system is routinely used in Immunohistochemistry (IHC). Extinction Coefficient 1% A280=32.0. Protein content: > 95%; Phycoethyrin (R-PE) is a 240 kDa phycobilliprotein found in red, macrophytic algae (seaweed). R-PE can be used with Fluorescein (FITC) for double labeling in flow cytometry using argon laser, since both R-PE and FITC can be excited at 488 nm, and R-PE fluoresces at a longer wavelength (580 nm) than FITC (520 nm). Phycoethyrin: R-PE purified from Poryhyra tenera; A565/A280 >5.0; A 1% 565 nm=82; Amax = 490, 545 and 566 nm; E max = 580 nm.
