carbomer 980 - is a commonly used wave series materials, carbomer is acrylic bonded allyl sucrose or pentaerythritol allyl ether polymers, usually in the form of loose white slightly acid powder, lower dosage can produce efficient thickening effect, which were very wide viscosity range and different rheological property of emulsion, cream, gel and transdermal preparations.different card's performance is slightly different, different models for different viscosity, a short rheological or long rheological said, such as: cabo 940 has a short rheological properties, in 0.5% of 63000 mpa viscosity. S, proper the product with high viscosity, cabo 941 has long rheological properties, in 0.5% viscosity reached 7500 mpa. S suitable for low viscosity products, carbomer corresponding models have no resistance to ion and ionic resistance performance.carbomer 980 has good thickening, high transparency, high viscosity, and strong suspension.carbomer 980 is widely used in daily chemical products, such as skin lotion, cream, transparent gel products, transparent skin gel, hair styling gel, shampoo, shower gel and disposable disinfection gel.notes:1. If the solution is used in the usual way, carbomer cannot be stirred when added to the water. Stirring while adding will cause carbomer to form a white water ball, and bubbles will be difficult to eliminate after neutralization;2. After the neutralization of carbomer, long time stirring or high shear stirring will cause viscosity loss;3. The presence of electrolyte will reduce the thickening efficiency of kapo resin;4. Long-term ultraviolet irradiation will reduce the viscosity of kapo resin.desheng technology is specialized in the collection of acrylate series of blood vessel separation adhesive, capom980, caps, mops and other surfactants and biological buffers.

CAPSContent:(Name)N-Cyclohexyl-3-aminopropanesulfonic acid(Chinese Name)3-()-1-(Abbreviation)CAPS(CAS#)1135-40-6(Molecular weight)221.32(Molecular formula)C9H19NO3S(Storage Conditions)Room temperature, keep away from light and moisture(Molecular structure)(Use)At present, the PVD transmembrane of protein has not used Tris-gly, SDS, 20% methanol buffer, because there is glycine in the buffer, so it is difficult to distinguish whether glycine is brought in by Buffer or the protein itself when sequencing. Now the transmembrane buffer used for sequencing is 10 mM/1 CAPS 10% methanol, and the methanol concentration range in CAPS imprint buffer is 0-20%. In general, the buffer with high methanol concentration is paired. The transfer efficiency of low molecular weight proteins is good, while the buffer with low or no methanol concentration is beneficial to the transfer of high molecular weight proteins.(Advantage)The purity (> 99%) is water-soluble, the process is stable, and the appearance of the product can be guaranteed to be pure white crystal powder.DeSheng is an old blood testing reagent company with 14 years of research and development experience.

piperazine-N, N '- bis (2-ethylsulfonic acid)       PIPESContent:(English name)PIPES(Chinese name)Piperazine-N, N '- bis (2-ethylsulfonic acid) / piperazine-1,4-diethylsulfonic acid(CAS#)5625-37-6(Molecular weight)302.368(Molecular formula)C8H18N2O6S2(Storage condition)room temperature, away from light and moisture(Molecular structure)(Application)This product can not form stable complex with most metal ions, and can be used as buffer in solution system containing metal ions. It was applied to the purification of tubulin by using cellulose phosphate chromatography. The purified recombinant GTP binding protein ARF1 and ARF2 were purified by gel filtration and used as buffer to crystallize ketoenzyme from E. coli. In addition, PIPES is not suitable for redox system because it can form free radicals. In cation exchange chromatography, a low concentration of PIPES buffer should be used, because pipes has relatively large ionic strength and its pKa value is concentration dependent.(Product advantage)The purity is >99%, with good water solubility and stable process, which can ensure that the product appearance is pure white crystal powder.Desheng is a chemical reagent company specializing in blood test reagents with 14 years of R&D experience, especially has a deep research on chromogenic substrate and biological buffer.
