Cy7.5 maleimide(non-sulfonated)
Catalog No.
A8142
Labeling of cysteine residues, as well as other thiolated molecules
Featured Products
Thiol-reactive, near infrared dye Cy7.5 for the labeling of protein SH groups.
Most proteins contain sulfhydryl groups which can be selectively labeled with maleimides. With this reagent, these proteins can be converted to near infrared (NIR) fluorescent conjugates. After it, the conjugates can be used in non-invasive live organism imaging to study distribution of the protein in tissues and organs.
