Choline chloride is a quaternary ammonium salt that serves as an essential precursor for acetylcholine synthesis and membrane phosphatidylcholine. It functions as a key methyl donor in one-carbon metabolism via conversion to betaine, supporting hepatic lipid transport and cell membrane structure. Adequate choline availability sustains lipid homeostasis and cholinergic neurotransmission in biological systems. [1]

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).
Pre-aliquoted for Longevity: Solid-state aliquots offer significantly longer shelf life compared to stock solutions, ensuring maximum stability for every use.
