This product is Arachis hypogaea (peanut) PNA lectin labeled with Biotium's superior CF®594 dye. Lectin PNA is specific for terminal β -galactose and binds preferentially to a commonly occurring structure, galactosyl (β -1,3) N-acetylgalactosamine. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Deep-red fluorescent CF®594 dye has excitation/emission at 593/614 nm.
