Carbomer 940-Aesthetic ingredients in skin care products Carbomer is composed of large polymer chains. The larger the chains, the greater their influence on the formulation of skin care products. It can control the viscosity, texture and appearance of cosmetics. Because of these beneficial properties, in addition to skin care and hair care products, it is also widely used in nail polish and personal care products. Today we will take a closer look at this product.
The role of NHS group in acridinium ester Some acridine esters or acridine sulfonamides contain NHS groups, which do not participate in the chemiluminescence reaction, but it is a key group for acridine esters to directly label and cross-link proteins, antibodies or enzymes, and can interact with Amine-reactive crosslinkers are widely used in acridinium ester, fluorescein and other biomolecular probes.
New Trinder's reagent for triglyceride detection The new Trinder's reagent is a chromogenic substrate for peroxidase, which is usually used for enzymatic detection of various biochemical indicators, such as the detection of triglycerides in serum. The principle is similar to that of ELISA, and the enzyme colorimetric method is first adopted. Detect, and then measure the result by spectrophotometer.
The similarities and differences of biological buffer CAPS and CHES CAPS, and CHES both biochemical and molecular Buffer reagents commonly used in experiments. Judging from the Chinese names, you might think that comparing them is very similar. Let's take a look at the similarities and differences between them.
How does HDAOS detect serum total cholesterol The new Trinder’s reagent is a type of chromogen substrate commonly used in biochemical reagents and in many types. The detection method is basically similar to the TMB in the ELISA kit, and both belong to the enzyme-catalyzed spectrophotometric detection. Different Trinder’s reagents have more or less differences in the detection of different biochemical indicators. Here is how HDAOS detects serum total cholesterol levels.
Chromogen substrate, chemiluminescence substrate and fluorescent substrate Diagnosis of enzyme preparations is a very important type of protein preparations in the field of IVD. There are many enzyme substrates, which can be basically divided into chromogenic substrates, luminescent substrates, fluorescent substrates, etc. The more representative ones are TOOS, TMB, and Lu Minol, fluorescein, etc.
