STEMCELL Technologies Collagenase Type I, Size: 100 mg
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 Type I contains the activity of several proteases, including collagenase, caseinase, clostripain, and trypsin. Collagenase Type I has been used for the digestion of human tissues such as intestine (Barthel et al.), mammary glands (Huss & Kratz), and prostate (Le et al.), as well as specific cell types such as endothelial cells (Ganguly et al.) and dorsal root ganglion cells (Dib-Hajj et al.).

Medchemexpress LLC Propargyl-PEG6-N3 | 1198080-03-3 | 100 MG
Propargyl-PEG6-N3 is a PEG-based PROTAC linker employed in the synthesis of PROTACs. It functions as a versatile click chemistry reagent, featuring an Azide group. This group readily participates in copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) when combined with molecules containing Alkyne groups. Furthermore, it can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules that possess DBCO or BCN groups, offering flexible synthetic pathways.
