Where is Sulforhodamine B powder usually used?
Sulforhodamine B powder is commonly used for cell viability detection, staining, and fluorescence staining techniques.
This product is a water-soluble protein dye that can bind to basic amino acids in intracellular proteins to form complexes. The amount of protein bound to the total protein in the cell can reflect the number of cells. The absorbance value measured at a wavelength of 515nm shows a good linear relationship with the number of cells.
What are the effects of Sulforhodamine B powder?
Sulforhodamine B powder has multiple effects, as follows:
Cell viability detection: SRB method is a cell viability detection method established by SKEHAN in 1990. It is widely used in the field of tumor research due to its advantages of speed, stable signal, and low cost. The National Cancer Institute in the United States has listed it as one of the standard anti-tumor screening methods.
Polar tracer: This highly water-soluble product can be used as a polar tracer for the study of cell morphology and neuronal cell-cell communication.
Dyeing Application: Used for dyeing wool, silk, nylon, as well as direct printing of wool and silk fabrics. It can also be used for dyeing bright red yarn products with acid light yellow 2G. It is also used for dyeing leather and paper.
In summary, this product has a wide range of application effects in fields such as biomedical research and dyeing industry.
