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.

Lumiprobe AF 488 DBCO, 5 mg Dibenzocyclooctyne (DBCO, DBCO, ADIBO)
Dibenzocyclooctyne (DBCO, DBCO, ADIBO) is one of the most reactive cycloalkynes for copper-free click reaction (SPAAC, strain-promoted azide-alkyne cycloaddition). The rate of interaction of DBCO with azides is significantly higher than that of other cyclooctynes, as well as Cu-catalyzed click reaction (CuAAC). Unlike other cyclooctynes, DBCO does not interact with tetrazines, which makes it possible to use it in bioorthogonal reactions together with trans-cyclooctenes and tetrazines.AF 488 is sulfonated rhodamine, a bright, photostable, and hydrophilic fluorophore that emits in the green channel. The absorption maximum is 495 nm. The emission maximum is 519 nm.AF 488 DBCO allows fluorescent labeling of azide-containing biomolecules inside living cells, whole organisms, and inanimate samples.
Cayman Chemical BIotIn-PEG3-azIde 5mg
A PEGylated version of biotin-azide that is more hydrophilic; can be used to label terminal alkynes via copper-catalyzed click reactions or copper-free click reactions with cyclooctynes; used to covalently tag proteins in combination with other tags

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.

LifeSensors SUMO Protease 2 5000U
For removal of SUMOpro3 tags from fusion proteins expressed from the following SUMOpro3 expression systems: (Cat.#s: 1010A, 1016, 1010K, 1011, 2151). SUMO Protease 2, a highly active and robust recombinant protease, cleaves hSUMO3 from recombinant fusion proteins. Unlike thrombin, EK, or TEV protease, which recognize short, linear sequences, SUMO Protease 2 recognizes the tertiary structure of huSUMO3. As a result, SUMO Protease 2 will not cleave within the fused protein of interest. By purchasing this product, the purchaser agrees to comply with the terms of our Limited Use Label License.

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.
