Kurzübersicht für LacI Antikörper (ABIN401451)

Target: LacI

Reaktivität: E. coli, Shigella sonnei

Wirt: Kaninchen

Klonalität: Polyklonal

Konjugat: Unkonjugiert

Applikation: Western Blotting (WB), Enzyme Immunoassay (EIA)

Produktdetails

Spezifität: 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.

Aufreinigung: Affinity Chromatography

Immunogen: Full-length recombinant Lac I protein

Isotyp: IgG

Anwendungsinformationen

Applikationshinweise: ELISA: 1/90,000-1/100,000. Western Blot: 1/500-1/2,000. Expect a band approximately approx. 38 kDa in size corresponding to Lac I by Western blotting inthe appropriate cell lysate or extract.
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.

Antigendetails

Target: LacI

Hintergrund: 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.Synonyms: JW0336, Lactose operon repressor, b0345
