- 特异性
- This product was affinity purified from monospecific antiserum by immunoaffinity chromatography. This antibody reacts with recombinant Lac I protein. A BLAST analysis was used to suggest cross-reactivity with Lac I from DNA-binding transcriptional repressor in Escherichia coli (strain DH10B) and transcriptional repressor of the lac operon in Shigella sonnei (strain Ss046) based on a 100% homology with the immunizing sequence. Cross-reactivity with Lac I from other sources has not been determined.

- 产品特性
- This antibody is designed, produced, and validated as part of a collaboration with the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. The lac repressor protein (Lac I) is an important genetic control protein. It controls the expression of the lactose metabolizing enzymes in Escherichia coli. This regulation involves specific recognition of the operator DNA sequence (Lac O) and consequent inhibition of transcription initiation by RNA polymerase, modulation of binding at this target site by small sugar molecules, inducers, provides the basis for regulation. Different ligand binding activities are associated with the isolated domains of Lac I: specific and nonspecific DNA binding with the NH2 termini, and inducer and specific DNA binding with the core protein. This antibody could possibly be used to recover and purify protein/nucleic acid complexes (host and viral proteins associated with the viral DNA) from infected cells.

- 应用备注
- This affinity purified antibody has been tested for use in ELISA and western blotting using recombinant Lac I protein. Specific conditions for reactivity and detection of Lac I should be optimized by the end user. Expect a band approximately ~38 kDa in size corresponding to Lac I by western blotting in the appropriate cell lysate or extract.
