Preparing Stock Solutions

The following data is based on the product molecular weight 495.19. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.02 mL 10.1 mL 20.19 mL
5 mM 0.4 mL 2.02 mL 4.04 mL
10 mM 0.2 mL 1.01 mL 2.02 mL
50 mM 0.04 mL 0.2 mL 0.4 mL

Programmed Cell Death

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
