General description

Anti-c-ErbB2/c-Neu (Ab-2), mouse monoclonal, clone 9G6, recognizes the ~185 kDa c-ErbB2/c-Neu SK-BR-3 cells and breast carcinoma. It is validated for IP and IHC on frozen and paraffin sections.
Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with SP2/0 Ag14 mouse myeloma cells. Recognizes the ~185 kDa c-ErbB2/c-neu protein.
Recognizes the ~185 kDa c-ErbB2/c-Neu in SK-BR-3 cells and breast carcinoma tissue. Does not cross-react with v-ErbB2 or the EGF receptor.

Immunogen

Human
cells overexpressing human c-ErbB2/c-Neu

Application

Frozen Sections (5 µg/ml)

Immunoprecipitation (1 µg/sample)

Paraffin Sections (see application references)

Warning

Toxicity: Standard Handling (A)

Physical form

Lyophilized from a volatile buffer, 100 µg BSA.

Reconstitution

Reconstitute the lyophilized antibody with sterile 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. Lyophilized antibodies should be reconstituted at 4°C with occasional gentle mixing for at least 2 h. Following reconstitution, refrigerate (4°C) for short-term storage or aliquot and freeze (-20°C) for long-term storage with 0.1% azide. Avoid freeze/thaw cycles of solutions.

Analysis Note

Negative Control
HepG2 cells or normal skin
Positive Control
SK-BR-3 cells or breast carcinoma tissue

Other Notes

Immunoprecipitates the ~185 kDa c-neu protein and has been reported to stain formalin-fixed paraffin-embedded tissue sections of human breast carcinomas overexpressing the c-neu protein. This antibody reacts with a cell surface epitope of c-neu but does not cross-react with the EGF receptor. In one study ductal carcinomas in situ displaying large-cell, comedo growth type, were stained while none of 16 ductal carcinomas in situ of small-cell, papillary, or cribiform growth type were stained by this antibody. Antibody should be titrated for optimal results in individual systems.
