Biological the intersection of general knowledge and trypsin digest cells ‘ Haidian Branch)

Trypsin digests cells

2015-08-17 Ask for the treasure living beings in the fields lying fallow in rotation

Contain albumen outside many kinds of afterbirth outside cells, such as the collagen, albumen these enable cells and the blake bottle inboard wall of sometimes cells are glued and linked up. Can make them separate after decomposing these proteins with trypsin, this course is named tryptic digestion function.

It is the cells growing sticking to the bottom of the bottle of cell to stick to wall cells, cells need going down to posterity after being covered with the bottom of the bottle, blow and beat cell to the intersection of cell and injury, greatly, need, digest with trypsin to it directly at this time, make cell and whom bottom of the bottle laminate so firm, can go on, blow and beat, make it fall off from bottom of the bottle at this time.

Trypsin digests function, after dealing with the animal to organize, can make the animal organize the other composition enzymolysis outside collagenous thread and cell among cells, get single cells. Generally digest cells and use 0.25% pancreas enzyme, and time must be grasped, digest, observe under microscope on one side, notice, can’t digest, lead to the fact damaging to cell instead. Collagenic protease can be used too besides trypsin, because pH activity of these two kinds of protease is more moderate.

The tryptic digestive juice kind of our company is overall, can meet most customer’s demands. Mainly push the products (T1300/T1320) Trypsin – EDTA digestive juice (and not include phenolsulfonphthalein including phenolsulfonphthalein) .

    Description of products :

    Train and take the place of organization cell of cell in the cultivation, disperse originally outside body to organize cell ‘ Will organize one to prepare and hang the liquid as single cells) And go down to posterity in the cultivation of cell, the digestion which is stuck wall growth cells should be used and organized digestive juice of cell when being dispersed. Commonly used digestive juice, for trypsin, EDTA,etc., function its to enable the intersection of protein and (ground substance outside the cell) among the cell mainly Hydrolyze, make, organize or stick to the intersection of wall and cell disperse single cell, make cells and hang liquid and is use for the further experiment.

    Ask for trypsin that the treasure of fields lying fallow in rotation produces – EDTA digestive juice (Trypsin-EDTASolution) Includes 0.25% pancreas enzyme and 0.02% EDTA (0.53mM) ,Soluble in, have calcium in the the intersection of magnesium and balanced the intersection of salt and solution, through filter, sterilize, can use for, train cell and digestion of organization directly. This product has convenient and fast, such characteristics as stability security, cell state are good. Usually can digest most walls cell when digesting for about 2 minutes at room temperature. Trypsin – EDTA digestive juice includes phenolsulfonphthalein and not includes 2 kinds of products of phenolsulfonphthalein, phenolsulfonphthalein has pH to point out function.

    Keep: -20 ¡æ is kept, effective 12 months.

      Operation method :

      1. Stick to the digestion of wall cells:

      a) Suck and train the liquid, or have no serum to train the liquid to wash cells once with aseptic PBS, Hanks liquid, in order to remove residual serum.

      b) Add a small amount of trypsin – EDTA digestive juice, cover cells, stands for 1-2 minutes at room temperature. Different cell digestion time is different to some extent, firm cells can lengthen digestion time appropriately for sticking to the wall.

      c) Observe under the microscope, cells obviously shrink, and the naked eye observes and trains the ware bottom to find the obvious change take place in the shape of cells; Or blow and beat cells with the rifle to find cells can just be blown and beaten. Absorb digestive juice at this moment. Add the cells containing serum and train the liquid, blow and lay cells, test in follow-up that can be used in directly.

      d) If find that it is insufficient to digest, can add trypsin – EDTA digestive juice to digest again.

      e) If find the digestion time of cell too long, has not blown and beaten cells yet, there are some to come off from training the ware bottom cells directly, train the liquid to blow and beat all cells with pancreas enzyme cells directly. 1000-2000g has been at odds with the community or the leadership for minute, precipitate cells, after trying hard to remove enzyme cell digestive juice of pancreas, add the complete cultivation liquid containing serum and suspend cells again, can be used in the follow-up experiment.

      2. The digestion organizing:

      Different? ? ? Organize the time in need of digesting to differ greatly, usually by can fully break up the organization after digestioning.

        Notes :

        1. Because tissues or cell properties are different, experiment personnel should be according to the detailed conditions, confirm the best digestion time; Digest the time of cell should not be too long, the state that otherwise will influence cells to stick to the wall and grow;

        2. Trypsin – EDTA digestive juice does not include and restrain fungus pharmaceutical, should pay special attention to operating aseptically in the course of using, prevent digestive juice from being polluted by the microorganism;

        3. Trypsin – the intersection of EDTA and digestive juice, should not 4 ¡ækeep for a long time, must guard against, freeze, melt repeatedly, a small amount advise, package, freeze, check while using;

        4. For your security and health, please wear the clothes of experiment and wear the disposable glove to operate

        T1300 trypsin – EDTA digestive juice (0.25%) Do not include phenol red solarbio 100ml
