introduction | acid red 52 is also called sulfonyl rhodamine B. Sulfonyl rhodamine B is an organic substance, dark red powder, soluble in water, and can be used for cell viability detection. Sulfonyl rhodamine B(sulforhodamine B,SRB) colorimetry using acid red 52 is a cell viability detection method established by SKEHAN in 1990. It has been widely used because of its advantages of rapidity, stable signal and low cost. Especially in the field of tumor research, the National Cancer Institute of the United States has listed it as one of the standard anti-tumor screening methods. |
Application | Sulfonyl rhodamine B is a pink protein binding dye, which can bind to basic amino acids in cell proteins under weakly acidic conditions, and under weakly alkaline conditions, Sulfonyl rhodamine B can be dissolved, and the absorbance value reflects the protein content, representing the number of cells. |
detection principle | sulfonyl rhodamine (Sulforhodamine B,SRB) is a water-soluble protein dye that can bind to basic amino acids in cells to form complexes. The amount of total protein in cells can reflect the number of cells. The absorbance values measured at a wavelength of 515nm showed a good linear relationship with the number of cells. |
use | acid rose red B is used for dyeing wool, silk and nylon and direct printing of wool and silk fabrics. It is bright red with fluorescence, very delicate and charming, with good levelness, but poor sun fastness and sensitive to water stains. It is only suitable for woolen fabrics with low color fastness requirements. It can be combined with acid light yellow 2G to dye bright red wool products, and is also used for dyeing leather and paper. It is mainly used for dyeing silk, nylon, wool and other fabrics. It can dye monochrome or color matching It is applied to fluorescence dyeing technology. |
production method | using m-hydroxydiethylaniline (m-diethylamino-phenol) and 2,4-disulfonic benzaldehyde (4-formyl-m-benzenedisulfonic acid) as raw materials, after condensation, Oxidation, salt product. The finished product is filtered, dried and crushed.. |
