Background	Lactose operon repressor (LacI) contains one HTH lacI-type DNA-binding domain, functions as a homotetramer. Lactose operon repressor as a repressor of the lactose operon, which also as an inducer, binds allolactose. If remove residues 1-59, resulting the loss of DNA-binding activity but retains tetrameric structure and inducer-binding activity. If delete residues 34-36, resulting the loss of tetramer formation, but retains dimer formation, inducer-binding activity, and DNA-binding activity.
Storage	Store the product under sterile conditions after opening at -20℃ to -80℃ for 12 months. Avoid repeated freeze-thaw cycles.
