Description: Cy3 maleimide is a selective and efficient fluorophore dye with low aqueous solubility. This labeling reagent can be used to attach Cy3 fluorophore to proteins and peptides which contain cysteine residues, as well as to other thiolate molecules (such as thiol-containing oligonucleotides).
Description: Cy5.5 maleimide is a thiol reactive dye which is capable of selective labeling of proteins which contain sulfhydryl groups. Cy5.5 maleimide has near infrared emission that makes it suitable for bioimaging applications.
Description: 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.
Description: Cy3.5 maleimide can be used for selective labeling of free sulfhydryl groups (e.g. cysteine residues in peptides, proteins and oligonucleotides). Before labeling, cystines should be prepared with reductant such as TCEP (tris-carboxyethylphosphine).
