Product Description: ALPS, as a novel Trinder's reagent with a CAS of 82611-85-6, is a chemical substance widely used in biochemical experiments. It has been further improved on the basis of traditional chromatography, such as changes in water solubility, reagent compatibility, stability, etc. Therefore, it can be applied in biochemical experiments to analyze the concentration of biological molecules such as nucleic acid and protein detection. ALPS color response The color reagent ALPS contains peroxidase, which can catalyze substrate oxidation reactions, resulting in color changes during the reaction process. This color change can intuitively reflect the concentration and purity of the substrate, allowing experimenters to quickly judge the results of the experiment. Application of ALPS Biochemical Experiment 1. Protein detection ALPS can be used for protein detection, as proteins are important biomolecules that can perform various functions within living organisms. In biochemical experiments, ALPS binds to proteins to form complexes and undergoes color changes during the reaction process. By measuring the color changes, the concentration and purity of proteins can be determined. 2. Nucleic acid testing Nucleic acid is a molecule contained in living organisms, including two types: DNA and RNA. In biochemical experiments, ALPS can combine with nucleic acid to form a complex, which reacts to generate a specific absorption wavelength. By measuring the color change, the concentration and purity of nucleic acid can be determined. more>

Product Description: Advantages of MES in aseptic culture: According to the results of MES buffer inhibiting the generation of superoxide in the root tips and affecting the root zone and growth of Arabidopsis, 0.01% and 0.1% of MES promote root growth from the early development stage of seedlings, while 1% of MES is inhibited. 2.1-2mMMES solution has excellent buffering ability and does not inhibit nodulation or reduce nitrogen fixation in soybean hydroponic culture. 5mMMES has no effect on the growth or absorption of most nutrients, and MES buffer can even enhance the potassium absorption of soybean seedlings without nodules. 3. In the study of MES, it was found that the combination of 10mgl-1 arabic gum and 3mMMES in NLN-13 significantly improved the efficiency of microspore embryogenesis in cabbage microspore culture under the influence of arabinogalactan protein at pH 6.4. In NH4 nutrition research, it was found that the addition of MES significantly increased plant yield and reduced node number at all concentrations; In the study on the effect of pH value on the rooting of apple micro bud stem segments, it was found that when MES was used as a buffer, the pH value was stable between 5.0-6.5. During the growth process of rice suspension culture, the addition of MES and proline in the culture medium has a significant impact on cell proliferation; After adding 500mgl-1 of PVP, casein hydrolysate, and MES buffer to the culture medium, a large amount of callus tissue was observed. In the study of early nodulation of annual alfalfa using MES buffer, it was found that a 0.5mM MES solution can stabilize the pH value by daily titration and using a high nitrate to ammonium ratio (9:1) in the solution. When used in MES for autotrophic micropropagation, the results showed that a fertilizer solution containing 5-mMMES buffer per 300mL container stabilized the pH value of the culture medium and improved the success rate of rooting. more>

Product Description: To better produce and use carbomer 980, we first need to understand its four basic elements: neutralization, viscosity, pH value, and turbidity. So controlling these factors is crucial. Neutralization and viscosity changes of carbomer 980 by different neutralizing bases In the neutralization process, with the addition of alkali, the pH value changes and the viscosity of gel also changes. When arginine, PC-2000, MD-100 and TEA are used as neutralizers, the viscosity of gel shows an overall upward trend with the increase of alkali, and there is only a small range of viscosity fluctuations at high pH values; When KOH is used as neutralizer, before reaching the neutralization point, the viscosity of gel gradually increases with the increase of alkali. If the amount of alkali continues to increase, the pH value of the system will exceed the neutralization point, and the viscosity of gel system will decrease; When NaOH is used as neutralizer, the viscosity of gel is relatively stable, and the gel can reach a relatively high viscosity at the initial stage of neutralization. It can be seen that NaOH in neutralizer has a strong thickening ability zui for Carbomer 980, and the viscosity of gel is less affected by the pH value of the system zui. Neutralization and viscosity changes of carbomer 980 at different concentrations The concentration of carbomer is different, and the initial pH value before neutralization is also different. The higher the concentration, the relatively lower the initial pH value. In the whole neutralization process, with the addition of alkali, the overall change trend of pH value of Carbomer 980 gel with different concentrations is consistent. The lower the concentration of Carbomer, the faster it reaches the neutralization point. The viscosity of gel is positively correlated with the concentration of carbomer. The higher the concentration, the higher the viscosity of gel. The viscosity of gel at the same concentration basically maintains the same level during neutralization. The influence of different electrolyte ions on the viscosity and pH value of Carbomer 980 Carbomer 980 gel is sensitive to electrolyte ions. The existence of electrolyte makes the viscosity of Carbomer 980 gel drop sharply, and the influence of divalent ions is greater than that of monovalent ions. Ions cause the viscosity of the Carbomer gel to decrease, mainly because it reduces the mutual repulsion force of the same charges on the main chain of the polymer, thus reducing the actual effective concentration of Carbomer in the system. Different ions have different effects on the viscosity of Carbomer gel, which is mainly related to the total charge number of ions in the solution. The univalent ions weaken the mutual repulsion through shielding charges, leading to the viscosity decline of Carbomer gel. In addition to this effect, the divalent ions will combine with Carbomer to form salts when their concentration is sufficient, thus further affecting the viscosity and transparency of the gel. The influence of different electrolyte ions on the turbidity properties of Carbomer 980 The introduction of electrolyte ions will also affect the transparency of the Carbomer gel system. Before the addition of electrolyte ions, the Carbomer 980 gel has a colorless and transparent appearance. With the increase of electrolyte ion concentration, the transparency of the gel system has changed, which is reflected in the increase of turbidity. The appearance of the gel system is translucent to opaque. more>
