Chlorophyll b is decomposed by chlorophyllase to form pheophytin b. This causes its color to change from green to olive brown. It is involved in the harvesting of light energy and its subsequent conversion into chemical energy during photosynthesis. Along with chlorophyll a, it plays a key role in the ability of plants to adapt to varying light intensities. The visible spectrum that is not absorbed when only chlorophyll a is present in the LHC.

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.
