General description

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 with Sp2/0.Ag14 cells (see application references). Recognizes the ~185 kDa c-ErbB2/c-Neu protein.
Recognizes the ~185 kDa c-ErbB2/c-Neu protein in HEK293 cells.

Immunogen

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

Application


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

Warning

Toxicity: Standard Handling (A)

Physical form

Lyophilized from 20 mM ammonium bicarbonate Buffer, 100 µg FAF-BSA.

Reconstitution

Reconstitue 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. Store at 4°C until reconstituted, then store in aliquots at -20°C or at 4°C with 0.1% azide. Freezing of aliquots is best for long term storage of reconstituted product; repetitive freezing and thawing should be avoided.

Analysis Note

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

Other Notes

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.

EGFR, ERBB2, ERBB3, and ERBB4 are growth receptors of the ERBB family implicated in the development of epithelial cancers. Studies have suggested a role for EGFR and ERBB3 in the development of prostate cancer (PC), while the involvement of ERBB2

Commonly used drugs for the treatment of breast cancer patients like paclitaxel and Herceptin often show severe side effects or induce resistance in clinical settings. Thus, we analysed a combination of Plk1 (polo-like kinase 1)-specific small interfering RNAs (siRNAs), a

Resistance to targeted therapies is an important clinical problem in HER2-positive (HER2+) breast cancer. "Drug-tolerant persisters" (DTP), a subpopulation of cancer cells that survive via reversible, nongenetic mechanisms, are implicated in resistance to tyrosine kinase inhibitors (TKI) in other malignancies

Human serum albumin (HSA) nanoparticles represent a promising tool for targeted drug delivery to tumor cells. The coupling of the antibody trastuzumab to nanoparticles uses the capability of human epidermal growth factor receptor 2 (HER2)-positive cells to incorporate agents linked

The tumor microenvironment contains multiple cancer-supporting factors, whose joint activities promote malignancy. Here, we show that epidermal growth factor (EGF) and estrogen upregulate in an additive manner the transcription and the secretion of the angiogenic chemokine CXCL8 (interleukin 8 [IL-8])
