Description

The 1B4C3 monclonal antibody recognizes human erbB3/HER3 also know as oncogene erbB3, tyrosine kinase cell surface receptor HER3, and C-erbB3. erbB3/HER3 is a receptor tyrosine kinase and a member of the epidermal growth factor receptor family. erbB3/HER3 binds the heregulin ligands and contains 4 furin-like repeats, 2 cheY receiver domains, and a tyrosine kinase domain with a predicted molecular weight approximately 148 kD. Signaling through the erbB3/HER3 receptor induces proliferation and differentiation in some cell types, the receptor is widely expressed in many tissues including kidney, lung, brain, placenta, skin and stomach. erbB3/HER3 forms constitutively active heterodimers with erbB2/HER2 in a subset of human mammary tumors; expression of erbB3/HER3 reported be linked to favorable outcome in bladder and ovarian cancer. erbB3/HER3 has been shown to interact with a number of proteins including EGF receptor, erbB2/HER2, erbB4, Grb2, Grb7, SOS1, cdk5, SHC, FAK, PTK6, and others. The erb3/HER3 receptor is extensively phosphorylated at residues T873 and S1123 (by cdk5); Y1199, Y1262, Y1289, and Y1328. The 1B4C3 antibody has been shown to be useful for flow cytometric detection of human erbB3/HER3.

Application

PG - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis and the oligomer sequence is confirmed by sequencing. TotalSeq™-B antibodies are compatible with 10x Genomics Single Cell Gene Expression Solutions.

To maximize performance, it is strongly recommended that the reagent be titrated for each application, and that you centrifuge the antibody dilution before adding to the cells at 14,000xg at 2 - 8°C for 10 minutes. Carefully pipette out the liquid avoiding the bottom of the tube and add to the cell suspension. For Proteogenomics analysis, the suggested starting amount of this reagent for titration is ≤ 1.0 µg per million cells in 100 µL volume. Refer to the corresponding TotalSeq™ protocol for specific staining instructions.

Additional Product Notes

TotalSeq™ reagents are designed to profile protein levels at a single cell level following an optimized protocol similar to the CITE-seq workflow. A compatible single cell device (e.g. 10x Genomics Chromium System and Reagents) and sequencer (e.g. Illumina analyzers) are required. Please contact technical support for more information, or visit biolegend.com/totalseq.

The barcode flanking sequences are GTGACTGGAGTTCAGACGTGTGCTCTTCCGATCTNNNNNNNNNN (PCR handle), and NNNNNNNNNGCTTTAAGGCCGGTCCTAGC*A*A (capture sequence). N represents either randomly selected A, C, G, or T, and * indicates a phosphorothioated bond, to prevent nuclease degradation.
