Anti-p53 (Ab-6) (Pantropic) Mouse mAb (DO-1)

Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with X63Ag8.653 mouse myeloma cells (see application references). Recognizes the ~53 kDa mutant and wild-type forms of p53.

Recognizes the ~53 kDa wild-type and mutant p53 protein in A431 cells and breast carcinoma tissue.

This Anti-p53 (Ab-6) (Pantropic) Mouse mAb (DO-1) is validated for use in Frozen sections, Gel Shift, Immunoblotting, ICC, IP, Paraffin sections for the detection of p53 (Ab-6) (Pantropic).

Epitope: Within amino acids 21-25 of human p53

Human

wild type, recombinant, human p53

Frozen sections (1 µg/ml; see application references)

Gel Shift (see comments)

Immunoblotting (0.1 µg/ml; see application references)

Immunocytochemistry (1-2.5 µg/ml; see application references)

Immunoprecipitation (1 µg/ml or use Cat. No. OP43A; see application references)

Paraffin sections (1 µg/ml, pepsin, heat or pressure cooker pre-treatment required; see application references)

Toxicity: Standard Handling (A)

Lyophilized from a volatile buffer, 100 µg BSA.

We recommend resuspending the lyophilized antibody with sterile phosphate buffered saline (PBS), pH 7.4, or sterile 20 mM Tris-saline (20 mM Tris containing 0.15 M NaCl), pH 7.4, to yield a final concentration of 100 μg/ml. Reconstituted product will be more stable if 0.1% sodium azide is added (do not add azide if antibody is to be used with viable cells). Lyophilized antibodies should be resuspended at 4°C with occasional gentle mixing for at least two hours. Following reconstitution, refrigerate (4°C) for short-term storage or aliquot and freeze (-20°C) for long-term storage.

Negative Control
SK-OV-3 cells or normal skin tissue

Positive Control
A431 cells or breast carcinoma tissue

Recognizes both mutant and wild-type p53 under denaturing and non-denaturing conditions. This antibody reacts weakly with rodent p53; we do not recommend it for rodent samples. For gel shift assay, resuspend in 100 µl of buffer. Wild-type p53 has a short half life and is present in low amounts in cells. For immunoprecipitation increasing the amount of sample and labeling with ³⁵S-Met for less than or equal to 1 h will aid in visualizing wild-type p53. Antibody should be titrated for optimal results in individual systems.
