Anti-c-ErbB2/c-Neu (Ab-3) Mouse mAb (3B5)

Anti-c-ErbB2/c-Neu (Ab-3), mouse monoclonal, clone 3B5, recognizes the ~185 kDa c-ErbB2/c-Neu protein in HEK293 cells. It is validated for WB, IF, 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 cells (see application references). Recognizes the ~185 kDa c-Erb2/c-Neu protein.

Recognizes the ~185 kDa c-ErbB2/c-Neu protein in HEK293 cells.

Human

a synthetic peptide (TAENPEYLGLDVPV) corresponding to amino acids 1242-1255 from the C-terminal domain of human c-ErbB2/c-Neu

Frozen Sections (2.5 g/ml)
Immunoblotting (2-3 g/ml, see application references)
Immunofluorescence (2.5 g/ml)
Immunoprecipitation (1 g/sample, see application references)
Paraffin Sections (2.5 g/ml, pressure cooker, heat or trypsin pre-treatment required, see application references)

Please refer to vial label for lot-specific concentration.

Toxicity: Standard Handling (A)

In 0.05 M sodium phosphate buffer, 0.2% gelatin.

Negative Control
HepG2 cells or normal skin

Positive Control
SK-BR-3 cells or breast carcinoma tissue

For paraffin sections, we recommend pre-treating with a pressure cooker, but trypsin and heat will also work well. Including 0.05% saponin during staining of paraffin sections may help reduce background. 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 cribriform growth type were stained by this antibody. Antibody should be titrated for optimal results in individual systems.
