生物活性

Bromocresol green sodium is an anionic dye. Bromocresol green sodium can be used for pH indication and DNA agarose gel electrophoresis. Bromocresol green sodium is also used in mammalian albumin measurement. Bromocresol green sodium deprotonates and produces the monoanionic form of yellow colour at lower pH (acidic condition), and produces dianionic blue colour at the basic condition[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
