Biological Activity

1,4-Diaminobutane dihydrochloride (putrescine dihydrochloride) is an essential endogenous polyamine and a key intermediate in the polyamine biosynthetic pathway. It serves as a precursor for the synthesis of spermidine and spermine, which modulate cell growth, proliferation, and gene expression. Through its roles in maintaining nucleic acid stability and regulating translation, 1,4-diaminobutane influences cellular survival and differentiation across various biological systems. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
