Protect from sunlight.3.Keep/Store only in original container.4.Never return spills in original containers for reuse.5. Keep away from: Food and feedingstuffs.6. The solution can be transported at room temperature, but temperatures exceeding 30 °C have to be avoided. Shipping should be completed within one week.7. The solution will still work beyond the expiry date, but a lower sensitivity has to be taken into account and a precipitate may occur.8. Contaminated or leaked out substrate solution from damaged bottles should not be used and has to be destroyed.3、Effective Components and Principle of FunctionA citrate buffer system (pH 4.5 - 5.0) contains the following effective components:Hydrogen peroxide3,3`,5,5`-Tetramethylbenzidine (TMB)precipitating reagentPeroxidase catalyses the decomposition of hydrogen peroxide, taking electrons from TMB (byoxidation). Oxidation of TMB forms a radical cation that stabilizes by dimerisation and shows the typical blue colour. This blue cation is stabilized by forming an insoluble complex with the precipitating reagent. So at positions with horseradish peroxidase activity a blue precipitate will appear. This precipitate is very fine so that even the smallest dots can be coloured regularly.4、Biosafety informationThis mixture is not classified as hazardous in accordance with Regulation (EC) No 1272/2008；Hazardous components：none (according to Regulation (EC) No 1907/2006 (REACH))5、Advantage1. Rapid precipitation2. Strong adherence to plastic surfaces3. Short reaction time4. Intensive dark blue colour5. Homogeneous staining pattern6、Instruction for usageFor bottling consider the following instructions:•Work in a dust free and darkened room.• Pay attention that the solution has no contact with metal parts (leading to catalysis) of yourinstruments. Closed systems of silicon tubes are favoured.• Clean all instruments and vessels very carefully.• Never touch parts of the instruments that are in contact with the solution with the naked hand. Wear powder free gloves.• Close the bottles immediately to minimize the influence of light and dust.• Use bottles that are not permeable to light, made from HDPE or PP.7. General Instructions for the Use on Microchips• This solution should only be used by qualified laboratory staff familiar with the basics of immunological methods.• Note: The substrate solution is very sensitive to impurities. This is why you should never immerse pipette tips in storage bottles. Unused solution is never returned to the bottle! Don't swap the bottles for the cups!• Substrate Solutions Test systems for instrumental measurements on glass or plastic surfaces (polycarbonate or polystyrene).• Depending on the system, it may be sufficient to wash the microarrays after incubation with the conjugate and then cover them with the substrate solution. Arrays can be developed with a rocking motion until visible color appears (approximately 5 to 10 minutes). Measurements can be performed using wet arrays or after washing with distilled water and drying. Dry microchips can be used for recording purposes. (Note: some glues will destroy colored deposits)...

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...
