Worthington collagenase. • CLSAFB contains higher collagenase and caseinase activities than CLSAFA. Worthington collagenase products CLS and CLSPA are assayed as described below: Method: A modification of the procedure of Mandl et al. Both genes have been cloned and sequenced (Yoshihara 1994). In addition tissue specific references and detailed isolation conditions can be found in the Worthington Tissue Dissociation Guide. Supplied as a dialyzed, lyophilized powder. 1975). The col H gene codes for type II collagenase, a 1021 amino acid peptide. Mar 4, 2024 · Collagenase Animal Free/AF is prepared from cultures grown in a medium devoid of animal based components with similar collagenase and secondary proteases to CLS-1 and CLS-2. com or TissueDissociation. Mar 4, 2024 · Worthington also offers 0. In 1959, the first commercially available collagenase isolated from Clostridium histolyticum was offered by Worthington. com. Store at 2-8°C. In addition, tissue specific references and detailed isolation conditions can be found in the Worthington Tissue Dissociation Guide. Correlations between enzyme type and effectiveness with different tissues have been good, but not perfect, due in part to the variable parameters of use. A detailed description of the Worthington collagenase and contaminant assays can be found in the Worthington Enzyme Manual. 22μm filtered collagenase preparations of each type in pre-packaged form for direct reconstitution and use in cell isolation and culture procedures. 22µm filtered preparations of each type in pre-packaged form for direct reconstitution and use in cell isolation and culture procedures. Please request your copy or go to Worthington-Biochem. Supplier: Worthington Biochemical Corporation LS004176 Prepared to contain higher clostripain activity. A detailed description of the Worthington collagenase and contaminant assays can be found in the Worthington Enzyme Manual. • CLSAFA is the original AFA grade designed to have collagenase and secondary proteases similar to Types 1 and 2 collagenase. Suggested for bone, heart, liver, thyroid and salivary primary cell isolation. Mar 4, 2024 · Collagenase (Animal Free) - Worthington Enzyme ManualCollagenase is produced by two separate and distinct genes in Clostridium histolyticum. Lungs from 4 mice were minced into ∼1 mm pieces using curved scissors and digested with 1 mg/ml collagenase type 1 (Worthington, cat# LS004194) and 1X dispase (Corning Mar 4, 2024 · In 1959, the first commercially available collagenase isolated from Clostridium histolyticum was offered by Worthington. Nevertheless most researchers consider the tissue-typing of partially purified collagenase lots to be a valuable service. Since true collagenase attacks the helical region of the molecule, change in optical rotary dispersion reflects collagen degradation (Keil et al. Nevertheless most researchers consider the tissue-typing of crude collagenase Worthington also offers 0. A specialized combination of Animal Free Clostridium histolyticum collagenase (Code: CLSAFB) and animal free Bacillus polymyxa neutral protease with a minimum of 250 CLS units and 2,000 caseinase units per mg dry weight. The col G gene codes for type I collagenase, a 936 amino acid peptide. These genes share 72% identity, and the proteins . At that time, only one preparation of crude enzyme was offered.
