About Cripto
Predicted to enable activin receptor binding activity and nodal binding activity. Predicted to be involved in several processes, including circulatory system development; determination of left/right symmetry; and nodal signaling pathway. Predicted to act upstream of or within several processes, including animal organ development; digestive tract morphogenesis; and endoderm development. Predicted to be active in cell surface and extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

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.
