What is the meaning of dispase?
What is the meaning of dispase?
Dispase is a protease which cleaves fibronectin, collagen IV, and to a lesser extent collagen I. It is found in some bacteria and can be isolated from culture filtrates of Bacillus polymyxa. It can be extracted, purified, and used in research.
How does dispase work?
Neutral Protease (Dispase) dissociates fibroblast-like cells more efficiently than epithelial-like cells so it has also been used for differential isolation and culture applications. Other advantages are its non-mammalian (bacterial) source and its ability to be inhibited by EDTA.
What is dispase II?
Dispase II (neutral protease) is an amino-endo peptidase that hydrolyzes the N-terminal peptide bonds of non-polar amino acid residues. This sequence is found with high frequency in collagen. Dispase II has a mild proteolytic action that makes it useful for the isolation and routine passaging of primary cells.
Is dispase an enzyme?
Dispase Enzymes A gentle enzyme that does not damage cell membranes, dispase is suitable for the separation of diverse tissues and cells that are grown in vitro and to prevent cell clumping for suspension cultures.
How do you dissolve dispase 2?
Incubate the fragments in the Dispase® solution (0.6 U/ml to 2.4 U/ml) at +37°C. – Make sure that the tissue fragments are well covered by the solution. Stir slowly at +37°C until the tissue is sufficiently dissolved.
How do you dissolve dispase?
Stir slowly at 37°C until the tissue is sufficiently dissolved. For compact tissues, we recommend incubating for 1 hour. Cells will not be adversely affected even after several hours in Dispase.
How do you dissolve Dispase?
How do you make a Dispase solution?
Prepare the Dispase Solution: Dissolve 2mg of Dispase into 1 ml of DMEM/F12. 9. Alternatively, make a 10x stock of Dispase (20mg/ml) and store in 1 ml aliquots in the -20C freezer. These aliquots can be thawed and diluted with 9mls of DMEM/F12.
How do you prepare dispase?
How do you reconstitute dispase?
Submerge tissue fragments in Dispase solution (0.6–2.4 U/mL) and incubate at 37°C. 4. Stir slowly at 37°C until the tissue is sufficiently dissolved. For compact tissues, we recommend incubating for 1 hour.
