KLH / PE / REA293

Product Details

Description	The REA Control (S) antibody clone REA293 is a universal isotype control that can be used with all recombinant engineered antibodies (REAfinity Antibodies) that recognize cell surface antigens. REAfinity Antibodies have been engineered for their high specificity and contain human IgG1 parts for constant regions. Although REAfinity Antibodies show virtually no binding to Fc receptors, the use of the clone REA293 is still recommended to control for other non Fc receptor–mediated non-specific binding of fluorochrome-conjugated REAfinity Antibodies to cells. Unspecific interactions of the fluorochrome with the cell surface can also be controlled for with conjugated versions of clone REA293.

About PE
Phycoerythrin (PE, R-PE) is a red-emitting fluorescent protein-chromophore complex that can be excited the 488-nm blue, 532-nm green, or 561-nm yellow-green laser with increasing efficiency and captured with a 586/14 nm bandpass filter. PE has an excitation peak at 565 nm and an emission peak at 578 nm. PE is 240kD in size and has an extinction coefficient of ~2x10^6 which makes it one of the brightest fluorophores available and a potent donor upon which to build tandem fluorophores with longer Stoke's Shifts.
