Buffer solution is a type of buffer system dedicated to life science research. In biochemical experiments, buffer solution plays an indispensable role. It can resist the influence of a small amount of strong acid and alkali from the outside, and maintain the system closest to the physiological environment. pH value. Both HEPES and PIPES buffers are commonly used buffers in biological experiments. The pH buffer range of HEPES is 6.8-8.2. It is a zwitterionic biological buffer. It is soluble in water and does not form stable complexes with metal ions. In most cases, it will not interfere with biochemical processes and can be widely used in a variety of Biochemical reactions and used as buffer reagents in certain cell culture media. HEPES is often used in the cell culture medium of various types of organisms; in protein research, PIPES is often used as the component and eluent of the binding buffer in cation exchange chromatography; in DNA research, PIPES is used as calcium phosphate and DNA The buffer for the precipitation formation system, AFM and the buffer for electroporation experiments. In addition, HEPES interferes with the reaction between DNA and restriction enzymes, and is not suitable for Lowry's method to determine protein content. HEPES buffer is often used in the research of organelles and highly variable, pH-sensitive proteins and enzymes, as well as in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. It is a hydrogen ion buffer that can control a constant pH range for a long time. The final concentration is 10-50mmol/L, and the buffering capacity can be achieved when the culture medium contains 20mmol/L HEPES. The pH buffer range of PIPES is 6.1-7.5, insoluble in water, soluble in NaOH aqueous solution. PIPES is different from buffers containing two (2-hydroxyethyl) amino groups (such as Bis-tris, Bicine), and can not form stable complexes with most metal ions. It is suitable for buffers in solution systems containing metal ions. According to existing research results, PIPES can be used to purify tubulin using phosphocellulose chromatography, to purify recombinant GTP-binding proteins ARF1 and ARF2 by gel filtration, and to use as a buffer to crystallize transketolase from E. coli. In addition, because PIPES can form free radicals, it is not suitable for redox systems. In cation exchange chromatography, a low concentration of PIPES buffer should be used, because PIPES has a relatively large ionic strength and its pKa value is concentration-dependent. We must learn to distinguish between the similarities and differences in these reagents, so as to better promote the development and production of our different products. Desheng unanimously adheres to this kind of subtle difference, so that it can continue to develop and produce better products.

Creatine kinase, muscle also known as CKM is a creatine kinase that in humans is encoded by the CKM gene. In the figure to the right, the crystal structure of the muscle-type M-CK monomer is shown. In vivo, two such monomers arrange symmetrically to form the active MM-CK enzyme. In heart, in addition to the MM-CK homodimer, also the heterodimer MB-CK consisting of one muscle (M-CK) and one brain-type (B-CK) subunit is expressed. The latter may be an important serum marker for myocardial infarction, if released from damaged myocardial cells into the blood where it can be detected by clinical chemistry.

After hologram glass master shouted by laser beam sensitive glass by 2D/3D master shooting system(or, have dot-matrix hologram recombined into big size on some plastic film) and had one sliver layer on the surface of the glass after slivering process, we have to put the hologram glass master into soft electronic forming tank to produce Hologram Technology Master origination which image is negative to final hologram sticker. After 70-90 minutes electronic forming, we'll get one hologram shim copy which is called nickel Hologram Technology Master origination(mother master) from the surface of glass master. Then we put the nickel Hologram Technology Master origination into another tank, hard electronic forming tank which can duplicate another piece positive operation hologram shim which is a little bit harder than soft shim for hard embossing and soft embossing. Small tank is for duplicating small master which is used to emboss hologram sticker and big tank is duplicating big master which is used to produce hologram film.

Intended use: AIVD COVID-19(SARS-CoV-2) IgG/IgM Rapid Test is a single use, rapid device for qualitative detection of total antibodies against 2019 novel coronavirus (SARS-CoV-2) in human serum, plasma or whole blood specimens. The kit is intended for screening of patients suspected for infection with SARS-CoV-2, and as an aid in the diagnosis of the coronavirus disease 2019 (COVID-19). Descriptionï¼? Novel coronavirus pneumonia (NCP) or SARS-COV-2, that was officially named by the WHO as â??Corona virus disease 2019â?? (COVID-19), is a respiratory infection caused by a new virus that was first identified in late 2019. IgM/IgG Rapid Kit can specifically detect IgM and IgG antibodies of COVID-19, covering the entire course of infection and recovery period of patients. This approach improves the overall diagnosis of COVID-19 in both acute and recovery phases of illness. This kit utilizes the principle of colloidal gold immunochromatography to qualitatively detect the new coronavirus (COVID-19) IgG / IgM antibodies in human serum and plasma. Lateral flow immunochromatographic assay provides an easy workflow, short turnaround time, and rapid diagnosis of COVID-19 suspected patients. This method does not require expensive medical instruments and consumables. Just take the specimen and add it to the sample well, and then add the required amount of a diluent. The IgG / IgM antibodies in the sample will interact with the colloidal gold-labeled COVID-19 recombinant antigen on the conjugate pad. Then the conjugate pad will release re-solubilized conjugate onto the nitrocellulose membrane. The nitrocellulose membrane (NC membrane) diffuses it forward. As the sample moves along the device binding reagents situated on the nitrocellulose membrane bind to the target at the test line. If the sample contains a COVID-19 IgG antibodies, they will bind to the colloidal gold-labeled novel coronavirus recombinant antigen, diffuse forward, and then react with the anti-human IgG antibodies immobilized on the NC membrane detection line (T2 line). Similarly, if the specimen contains IgM antibodies to COVID-19, the antibodies will react with antigen-coated particles, the conjugate migrate laterally forward, and cause a colored line (T1 line). The darker the color of colloidal gold on the test line, the higher the concentration antibodies to COVID-19 in the sample. Accuracy:ï¼?> 90% Specificity: 97% Basic Protocolï¼? 1. Remove the test specimen, required reagents from storage conditions, and equilibrate to room temperature. 2. Unpack the aluminum foil bag, place the test horizontally on the table and number it. 3. Add 10ul serum, plasma or whole blood sample to the sample well with a pipette or a dropper. Slowly add 2 drops of sample dilution (about 60uL) to the sample well. 4. Read the results within 10-15 minutes after adding the sample, and the results will be invalid after 30 minutes.
