Cy5-SE (Cy5 NHS Ester) triethylamine salt 一种用于标记肽, 蛋白质, 寡核苷酸的氨基基团的反应染料 (Ex=649 nm; Em=670 nm)。

Cy5-SE (Cy5 NHS Ester) triethylamine salt is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides. Cy5-SE triethylamine salt is ideal for very cost-efficient labeling of soluble proteins, as well as all kinds of peptides and oligonucleotides Ex=649 nm; Em=670 nm).

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Conjugation of SELP Analogues with Cy5-SE.
1. 1 mL of each 100 μg/mL SELP solution in 100 mM sodium bicarbonate buffer (pH 8.3) is mixed with 10 μL of 1.2 mg/mL Cy5 mono NHS-ester in 10% DMSO and incubates for 2 hours on ice.
2. To quench the reaction, 50 μL of 1 M Tris-HCl (pH 8.0) is added to the reaction solution.
3. Reaction mixtures are loaded onto 1.5 mL Sephadex G-25 columns, and Cy5-conjugated SELPs are eluted by centrifugation for 3 minutes at 1050g. has not independently confirmed the accuracy of these methods. They are for reference only.
