Protein Labeling Reagents
Biotium MB succinimidyl ester
The amine reactive succinimidyl ester of MB (methylene blue) can be conjugated to peptides, proteins, drugs, polymeric materials and biomolecules with primary amine groups. The conjugate will have a blue color and be able to complex with nucleic acids. Methylene blue is a well known redox dye which can be reversibly reduced to its colorless leuco form. Upon oxidation, the blue color of the dye is recovered.
Biotium CF568 succinimidyl ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Red fluorescent CF568 dye has excitation/emission at 562/583 nm.

Medchemexpress LLC Apn-PEG36-tetrazine | 1997.30 g·mol⁻1 | C94H161N7O38 | 10 MG
APN-PEG36-tetrazine is a tetrazine-functionalized polyethylene glycol (PEG36) reagent for bioorthogonal click chemistry and antibody-drug conjugate (ADC) linker development. It undergoes inverse electron-demand Diels-Alder (iEDDA) reactions with trans-cyclooctene (TCO) groups, enabling rapid conjugation in bioconjugation workflows. The reagent is supplied in small research quantities and should be stored protected from light under inert conditions.
- Tetrazine-functionalized PEG36 for iEDDA click reactions.
- Suitable for antibody-drug conjugate (ADC) linker synthesis and bioconjugation.
- Molecular weight approximately 1997.30 g·mol⁻1.
- Available in small vial sizes for research use (1 mg, 5 mg, 10 mg).
- Store at -20°C protected from light; in solvent store at -80°C for long-term stability.
