Recombinant human NRG1 (Heregulin) EGF Domain (Cat. No. 551904) (black circles) induces proliferation of MCF-7 cells. Ultra- LEAF™ purified anti-human NRG1b-EGF (clone W17087B) (purple squares) neutralizes MCF-7 cell proliferation induced by recombinant human NRG1 (Heregulin) EGF Domain at 10 ng/mL in a dose-dependent manner, whereas the Ultra-LEAF™ purified rat IgG2b, κ isotype control (Cat. No. 400644) (gray triangles) does not have the effect. ND50 range is 2 - 15 µg/mL.

Neuregulin 1 (NRG1) was initially identified in the conditioned medium of a human breast tumor cell line as a protein of 45 kD, which induces the phosphorylation of a tyrosine kinase (ERBB2). The neuregulin family includes four members (NRG1-NRG4) that are encoded from four individual genes. Through differential promoter usage and splicing, these members generate 12 isoforms. The best characterized is neuregulin 1, which includes eight isoforms; all isoforms contain (from N-terminus to C-terminus) an immunoglobulin-like (Ig) domain, a growth factor-like domain (EGF), a transmembrane (TM), and a cytoplasmic domain. Alternative splicing in the EGF-like domain of neuregulin 1 results in α and β isoforms. The EGF-like domain is necessary and sufficient for neuregulin bioactivity. The EGFR family of receptors includes four members (ErbB1 through ErbB4), and neuregulins bind to the ErbB3 and ErbB4 receptors. Neuregulins are released from the membrane by proteolytic cleavage, and this process is required for the binding of the neuregulin derived fragments to ErbB receptors. The neuregulin1-β isoform is predominant in the central nervous system and participates in development, survival, and metabolism in neuron and glial cells. Neuregulin1-β is neuroprotective and attenuates inflammatory responses induced by ischemic stroke in rats, preventing macrophage and microglial infiltration and astrocytic activation. Also, neuregulin1-β blocks the induction of pro-inflammatory and stress genes provoked by ischemia. Neuregulins 1-4 are expressed in approximately 25% of breast cancer carcinomas and increase breast cancer cell proliferation, increase tumorigenesis, and promote invasive characteristics of cancer cells. In this sense, neuregulin1-β induces MMP-1 and MMP-9 in cancer cell lines.

Related FAQs
- Do you guarantee that your antibodies are totally pathogen free?
-
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
-
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
-
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
-
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
