| Description | Anti fluorescence quencher is a reagent that can slow down fluorescence quenching. It can be used in most fluorescent dyes with simple operation. This product is recommended to be used in fixed permeabilized cells or tissues. After observation, nail polish or sealant can be used to seal the edge of Anti fluorescence quencher is a reagent that can slow down fluorescence quenching. It can be used in most fluorescent dyes with simple operation. This product is recommended to be used in fixed permeabilized cells or tissues. After observation, nail polish or sealant can be used to seal the edge of the coverslip; DAPI containing antifluorescent quencher can directly stain nuclei. Presentation：Before using the product, return it to room temperature, slightly shake and mix to avoid bubbles.1.Cell samples : ( 1 ) After dyeing, absorb the liquid. ( 2 ) Add 10-20 µL anti-quenching agent to each glass slide, cover the cover glass with cells, and let the cells contact the anti-quenching agent. When the cover glass is covered, the excess can be squeezed out. The anti-quenching agent, try not to have bubbles. ( 3 ) Fluorescence microscope observation. ( 4 ) ( optional ) : After the observation, nail polish or sealant can be used to seal the edge of the cover glass. 2. Tissue sections : ( 1 ) After the staining is completed, the staining solution is sucked off. ( 2 ) Drop 10-20 µL of anti-quenching agent on the tissue section, cover the cover glass, let the section contact the anti-quenching agent, and squeeze out the excess anti-quenching agent when cover the cover glass to avoid bubbles as much as possible. ( 3 ) Observation of tissue sections by fluorescence microscope. ( 4 ) ( optional ) : After the observation, nail polish or sealant can be used to seal the edge of the cover glass. 3.Other samples : Other samples can be operated with reference to the above samples. Matters needing attention：1. the anti fluorescence quencher has poor anti quenching effect on staining live cell membrane dyes and mitochondrial dyes. It is recommended that the anti fluorescence quencher be used to fix permeabilized cells or tissues. 2. when the anti fluorescence quencher is matched with our YF 488 dye, there may be background interference. This situation may be caused by adding too much of this product. The amount of this product should be minimized. 3. the anti fluorescence quencher may not be suitable for some dyes. Pre experiment is recommended to test the matching before the experiment. 4. for your safety and health, please wear experimental clothes and disposable gloves.Scope of application：Fluorescent Mounting Media...

The molecular weight is 34,500 daltons, the pH optimum is 8.0, and pI is 6.0.Carboxypeptidase B is competitively inhibited by arginine and lysine. The enzyme is Carboxypeptidase B catalyzes hydrolysis of the basic amino acids lysine, arginine and histidine from theC-terminal end of polypeptides. The molecular weight is 34,500 daltons, the pH optimum is 8.0, and pI is 6.0.Carboxypeptidase B is competitively inhibited by arginine and lysine. The enzyme is also inhibited by metal chelating agents, e.g., EDTA. Recombinant Carboxypeptidase B (EC 3.4.17.2) is expressed in E.Coli and purified by high pressure liquid chromatography. There is no trace of other enzyme (such as carboxypeptidase A and chymotrypsin) activity. No protease inhibitors such as PMSF are present in the preparation.Animal origin free:eliminate the risk of virus presence, or of any other potential adventitious agents found in animal-derived carboxypeptitase B.Stability:A sterile recombinant carboxypeptidase B lyophilized eliminates the risk of contamination and decreases the chances of activity loss in the process of transport and storage. High purity:1) Recombinant carboxypeptidase B provides increased specific activity and eliminates contaminating protease activities found in extracted enzymes with lower purity level. 2) No other contaminating proteases such as chymotrypsin and carboxypeptidase A. 3）Less than 10ppm of recombinant trypsin...
