DBCO-PEG4-NHS Ester for biomolecular labeling

Catalog Number: (76485-036)

Supplier: AAT BIOQUEST INC

Description: Cu-free click reaction, i.e., the strain-promoted alkyne-azide cycloaddition (SPAAC) is a bioorthogonal reaction utilizing a pair of reagents, cyclooctynes and azides that exclusively and efficiently react with each other while remain inert to naturally occurring functional groups such as hydroxy, amino and thiol groups.

5-Carboxy-X-rhodamine, NHS ester ≥95%

Catalog Number: (103010-822)

Supplier: Anaspec Inc

Description: Single isomers of ROX are increasingly preferred for labeling peptides and nucleotides because they give better resolution in HPLC purifications that are often required in bioconjugations. Variable ratios of the 5- and 6-isomers often cause complications in the interpretation of labeling results and assay performances.

5(6)-Carboxyfluorescein N-hydroxysuccinimide ester (5/6-FAM SE)

Supplier: Anaspec Inc

Description: Although FITC reagents have been more often used to prepare fluoresceinated bioconjugates, the low stability of FITC bioconjugates makes some researchers use amine-reactive succinimidyl esters of carboxyfluorescein (commonly called FAM) in bioconjugations. FAM reagents give carboxamides that are more resistant to hydrolysis. We have shown that FAM reagents require less stringent reaction conditions and give better conjugation yields, and the resulted conjugates have superior stability. We noted that FITC labeled peptides tend to deteriorate more quickly than the corresponding FAM conjugates.
