Gene Information

Escherichia coli ... PhoA(945041)

Specificity

Alkaline phosphatase (AP). MAB1012 has a high affinity and recognizes an AP determinant resistant to denaturation by SDS-PAGE. It is therefore ideally suited for sensitive and specific detection of AP fusion proteins by Western blot analysis of E. coli transformants expressing fusion products.

Immunogen

Epitope: E. coli, bacterial only
F201C1B

Application

Anti-Alkaline Phosphatase Antibody, E. coli, bacterial only detects level of Alkaline Phosphatase & has been published & validated for use in IP, WB & IC.
Western blot at 1:5,000. 42-45kDa on SDS-PAGE,reducing gels for natural E. coli alkaline phosphatase monomer. Alkaline phosphatase fusion proteins will vary depending upon the target fusion protein.

Immunocytochemistry: reacts with E.coli. AP fusion protein targets in acetone fixed cell preparations. 1:4000, other fixatives or conditions untested.

ASSAY:

Preparation of E. coli TnphoA transformants: E. coli strain CC118 was transformed with plasmid pGEM-3Z containing TnphoA insertional mutations in the p101 gene of Mycoplasma hyorhinis, which encodes a protein with a typical N-terminal prokaryotic single peptide (Yogev et al. 1991).

Identification of fusion protein with MAB1012 transformants: Transformants are grown in 2XYT medium to OD600=0.6. Cells were centrifuged 3 minutes at 10,000 x g, suspended in SDS-PAGE sample buffer, heated at 100°C for 5 minutes, frozen and thawed and centrifuged as above at room temperature to remove insoluble material. The sample is applied at 9% to a SDS-PAGE gel, and Western immunoblot is performed as described (Yogev et al. 1991).

Immunoprecipitation: 5μL of antibody per 500μL of lysate in RIPA or 0.5% triton X-100 solutions.

Optimal working dilutions must be determined by end user.

Physical form
