Medchemexpress LLC 2,5-dioxopyrrolidin-1-yl 1-(4-(tetrazin-3-yl)phenyl)-3,19-dioxo-PEG4-SS-oate | 95.0% | 723.82 | C30H41N7O10S2 | 10 MG
Tetrazine-PEG4-SS-NHS is a cleavable PEG4-based heterobifunctional linker containing a tetrazine reactive group, an NHS ester for amine coupling, and a disulfide cleavable bond for release. It is designed for bioconjugation and antibody-drug conjugate synthesis, enabling rapid click conjugation and controlled intracellular release.
- Cleavable disulfide linkage for intracellular release.
- Tetrazine group enables rapid iEDDA click conjugation with trans-cyclooctene reagents.
- NHS ester enables efficient coupling to primary amines.
- PEG4 spacer improves solubility and reduces steric hindrance.
- Available in small milligram quantities for research use.
Medchemexpress LLC Desthiobiotin-NHS ester | 80750-24-9 | MFCD08062086 | >98.0% | 311.33 | C14H21N3O5 | 1 G
Desthiobiotin-NHS ester is an NHS-activated desthiobiotin reagent that reacts with primary amines to form stable amide bonds, enabling reversible affinity capture with streptavidin in labeling and bioconjugation workflows. Supplied as a dry powder with recommended low-temperature storage, it is used for protein labeling, biochemical assays, and metalloprotein probing.
- Reacts with primary amines to form stable amide bonds.
- Enables reversible streptavidin-based capture due to lower affinity than biotin.
- Suitable for protein labeling, bioconjugation, and biochemical assays.
- Supplied as a powder with recommended low-temperature storage.
- High purity for reliable conjugation performance.

Sigma Aldrich Fine Chemicals Biosciences Phalloidin Atto 390 suitab
Atto 390 Phalloidin is a novel fluorescent label with a coumarin structure. The dye is intended for application in the area of life science e.g. labeling of DNA RNA or proteins. Characteristic features of the label are high fluorescence quantum yield large Stokes-shift good photostability and low molecular weight.Phalloidin is a fungal toxin isolated from the poisonous mushroom Amanita phalloides. Its toxicity is attributed to the ability to bind f actin in liver and muscle cells. As a result of binding phalloidin actin filaments become strongly stabilized. Phalloidin has been found to bind only to polymeric and oligomeric forms of actin and not to monomeric actin. The dissociation constant of the actin-phalloidin complex has been determined to be on the order of 3 x 10-8. Phalloidin differs from amanitin in rapidity of action at high dose levels death of mice or rats occurs within 1 or 2 hours.
