MW: 238.30 gr/mol
MF: C9H18O5S
IPTG Powder, well also known as Isopropyl β-D-1-thiogalactopyranoside, it acts as an allolactose analogue which stays unmetabolized within cells. It plays a key role in the molecular biology by inducing overexpression of recombinant proteins which controlled by the lac promoter in the Escherichia coli.
When was introduced to bacterial cultures, The IPTG like binds to the lac repressor protein. Thereby blocking its inhibition for gene expressions. So, this Allowing for precise Controls over production for large quantities of the targeted protein.
Researchers widely use IPTG Powder in lab to induce protein expression. In bacterial cultures aiding in studies for protein, functions, structures, and interactions.
