STEMCELL Technologies Collagenase Type III, Size: 5 g
Collagenase is a protease consisting of a single polypeptide chain approximately 1000 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 Type III contains low levels of proteolytic activity especially for caseinase clostripain and trypsin. Collagenase Type III has been used for the digestion of mammary glands (Rønnov-Jessen et al.) colon cancer stem cells (Prince et al.) and breast epithelial tumor cells (Chan et al.).
STEMCELL Technologies Collagenase Type V, Size: 5 g
Collagenase is a protease consisting of a single polypeptide chain approximately 1000 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 Type V contains high levels of collagenase and caseinase activities.
Medchemexpress LLC Dbco-peg24-nhs ester | 2765066-38-2 | C74H119N3O30 | 5 MG
DBCO-PEG24-NHS ester is a click chemistry reagent that reacts specifically and efficiently with primary amines at neutral or slightly basic conditions to form a covalent bond. DBCO is commonly used for copper-free Click Chemistry reactions. It is for research use only.
- The hydrophilic PEG spacer arm improves water solubility
- Provides a long and flexible connection that minimizes steric hindrance involved with ligation
LifeSensors SUMO Protease 1 5000 Units
LifeSensors' industry leading SUMO Protease 1 (Ulp1), a highly active and robust recombinant protease, cleaves SUMO from recombinant fusion proteins. Unlike thrombin, EK, or TEV protease, which recognize short linear sequences, SUMO Protease 1 recognizes the tertiary structure of SUMO. As a result, SUMO Protease 1 will not cleave within the fused protein of interest. 1 unit will cleave >90 ¿g of hSUMO3-GFP in 1 hr at 37C.
