Preparing Stock Solutions

The following data is based on the product molecular weight 405.9. Batch specific molecular weights may vary from batch to batch due to the degree 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
0.2 mM 12.32 mL 61.59 mL 123.18 mL
1 mM 2.46 mL 12.32 mL 24.64 mL
2 mM 1.23 mL 6.16 mL 12.32 mL
10 mM 0.25 mL 1.23 mL 2.46 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.

Pathways for CFM 4


Apoptosis Signaling Pathway

Apoptosis is a physiological process for cell death that is critical during aging and development. It may also be referred to as cell 'suicide'. Apoptosis can be triggered by events both inside and outside of the cell.
