Medchemexpress LLC 1H-Thieno[3,4-d]imidazole-4-pentanamide, N-[19-(11,12-didehydrodibenz[b,f]azocin-5(6H)-yl)- | 1255942-07-4 | 99.49% | 50 MG
DBCO-PEG4-Biotin is an azadibenzocyclooctyne-biotin derivative that contains a biotin group and four PEG units. It functions as a versatile biotinylation reagent, enabling the introduction of a biotin moiety to azide-labeled biomolecules. This process occurs through a copper-free strain-promoted alkyne-azide click chemistry (SPAAC) reaction. It is a click chemistry reagent, featuring a DBCO group that facilitates strain-promoted alkyne-azide cycloaddition (SPAAC) with azide-containing molecules.
- Azadibenzocyclooctyne-biotin derivative
- Contains a biotin group and 4 PEGs
- Versatile biotinylation reagent
- Used for introducing a biotin moiety to azide-labeled biomolecules
- Utilizes copper-free strain-promoted alkyne-azide click chemistry (SPAAC)
- Contains a DBCO group for SPAAC with azide groups

Medchemexpress LLC Cholesterol-PEG-maleimide | 95.1% | 2000 Da (average) | 50 MG
Cholesterol-PEG-maleimide (average MW 2000) is a cholesterol-terminated polyethylene glycol with a terminal maleimide group. It is a solid PEGylated lipid that self-assembles in water and is used to prepare liposomes, nanoparticles, and to conjugate thiol-containing molecules via stable thioether bonds.
- Maleimide-functionalized PEG for thiol-specific conjugation.
- Average molecular weight 2000 Da provides steric stabilization and PEGylation.
- Solid powder form suitable for liposome and nanoparticle formulation.
- Enables formation of stable thioether linkages with thiol-containing molecules.
- Storage as powder at -20°C supports long-term stability.
STEMCELL Technologies Collagenase B, ACF, Size: 100 mg
Collagenase B, Animal Component-Free (ACF) is obtained from cultures free of animal-derived materials. Collagenase is a protease consisting of a single polypeptide chain approximately 1,000 amino acid residues in length. Collagenase is capable of digesting native collagen fibrils commonly found in connective tissues and therefore is frequently used for tissue dissociation. Collagenase preparations contain the activity of several proteases, including collagenase, caseinase, clostripain, and trypsin (Kessler & Yaron). Collagenase B, ACF contains higher collagenase and caseinase levels than Collagenase A and is intended for use in applications where it is necessary to prevent the introduction of potential animal-derived pathogens.

Cayman Chemical -BIotIn-PEG3-amIn 100mg
A synthetic intermediate; has been used in the synthesis of biotinylated siderophores for whole-cell bacterial pull-down assays, as well as in the synthesis of protein-polysaccharide conjugate vaccines for S. pneumoniae
Medchemexpress LLC PEG5-Tos | 155130-15-7 | 96.9% | 392.46 | 1 G
PEG5-Tos is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. PROTACs (Proteolysis Targeting Chimeras) consist of two different ligands connected by a linker; one ligand targets an E3 ubiquitin ligase, and the other targets the protein of interest. PROTACs utilize the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- For research use only
