Biotin-PEG3-azide is an azide-functionalized biotinylation reagent with a triethylene glycol spacer designed for efficient click chemistry conjugation. It enables both copper-catalyzed and strain-promoted azide-alkyne cycloaddition to label proteins, nucleic acids, or small molecules for detection, affinity capture, or construction of bifunctional assemblies. Supplied as a high-purity solid, it is intended for bioconjugation and linker synthesis.
- Azide-functionalized biotin for click chemistry.
- Triethylene glycol spacer improves solubility and reduces steric hindrance.
- Supports copper-catalyzed and strain-promoted azide-alkyne cycloaddition.
- High purity suitable for bioconjugation applications.
- Solid form with recommended cold storage for stability.

Sigma Aldrich Fine Chemicals Biosciences Collagenase B from Clostri
Collagenase B is prepared from Clostridium histolyticum cultures by filtration ammonium sulfate precipitation dialysis and lyophilization. Collagenase from Clostridium histolyticum is a collagenolytic enzyme. It interacts with collagen-like substances and is responsible for the degradation of collagen into small peptides. It is widely used for the disaggregation of many types of tissues (e.g. lung heart muscle bone adipose tissue liver kidney cartilage mammary gland placentae blood vessels brain tumors) and for the preparation of single-cell suspensions for the establishment of primary cell culture systems. Collagenase B is recommended when yield and viability are important.
