Abcam Biotin-de x tran, 10MG
MW 73400 g/mol, Purity >98%. Membrane impermeant dextran conjugate containing covalently attached biotin molecules (Vitamin H) making it useful in streptavidin/avidin assay systems. The attached biotins are commonly used haptens that can be detected by using its strong affinity for the proteins avidin (from egg white) or streptavidin. This conjugate contains approximately 12 biotin groups/dextran (based on amine assay; with approx. 1 amine/40 glucose residues). The excess amino groups are not capped, and they can be further labeled with a fluorophore, or can be fixed in place with formaldehyde, lysine or glutaraldehyde, allowing subsequent tissue processing, such as sectioning.

Medchemexpress LLC DBCO-NHS ester 2 1g | 1384870-47-6 | 1 G
DBCO-NHS ester 2 is a dibenzoazacyclooctyne (DBCO)-containing N-hydroxysuccinimide (NHS) ester reagent for strain-promoted alkyne-azide cycloaddition (SPAAC). It is used to install a DBCO handle on amine-containing molecules for copper-free click conjugation to azide-functionalized partners and as a cleavable linker in bioconjugation workflows.
- Amine-reactive NHS ester for efficient coupling to primary amines.
- DBCO group enables strain-promoted copper-free click chemistry with azides.
- Suitable for bioconjugation and linker formation in antibody-drug conjugates.
- High reported purity for reproducible conjugation performance.
- Supplied as a 1 g quantity for small-scale synthesis and labeling.
