Product Description
|
Analog of microcystin-LR (Prod. No. ALX-350-080) with Trp substituted in place of Arg. Hydrophobic and believed to be more cell permeable than other microcystins. May prove useful in biochemical studies in intact cells. Microcystin-LW has a characteristically different absorption spectrum compared to other microcystins, making it a useful reference compound for HPLC analysis. The Trp confers an absorption maximum at 222nm, whereas most microcystins h***e a characteristic maximum at 239nm. |
