Application

Magnesium acetate is used in molecular biology applications such as batch in vitro transcription of RNA and the crystallization of transcription factor:DNA complexes and proteins via the sitting-drop vapor-diffusion method.
Magnesium acetate solution has been used:
  • to supplement Midkin fused to the biotin ligase BioID2 (MK-BioID2) conditioned medium for in-tube biotinylation assay
  • as a component of lysis buffer and amplified RNA (aRNA) fragmentation buffer to perform aRNA fragmentation
  • as a component of lysis buffer and DamID buffer for sequencing zygote samples
