ACTIVITY TEST of the Active Neuregulin 1 (NRG1)
NRG1 (Neuregulin-1) is a membrane glycoprotein that belongs to the neuregulin family and act on the EGFR family of receptors. It mediates cell-cell signaling and plays a critical role in the growth and development of multiple organ systems. It is reported that by binding to HER3 receptor, NRG1 mediates downstream signaling pathways, leading to multiple effects including growth, proliferation, decreased apoptosis, cellular migration and angiogenesis. Thus, proliferation assay of NRG1 was conducted using MCF-7 cells. Briefly, MCF-7 cells were seeded into triplicate wells of 96-well plates at a density of 2,000cells/well and allowed to attach overnight, then the medium was replaced with serum-free standard DMEM prior to the addition of various concentrations of NRG1. After incubated for 72h, cells were observed by inverted microscope and cell proliferation was measured by Cell Counting Kit-8 (CCK-8). 10µL of CCK-8 solution was added to each well of the plate, the absorbance at 450nm was measured using a microplate reader after incubating the plate for 1-4 hours at 37oC.
(A) MCF-7 cells cultured in DMEM, stimulated with 10ng/mL NRG1 for 72h;
(B) Unstimulated MCF-7 cells cultured in DMEM for 72h.
Figure. Cell proliferation of MCF-7 cells after stimulated with NRG1.
The dose-effect curve of NRG1 was shown in Figure 2. It was obvious that NRG1 significantly promoted cell proliferation of MCF-7 cells. The ED50 for this effect is typically 5.240 to 9.112 ng/mL.

USAGE of the Active Neuregulin 1 (NRG1)
Reconstitute in 20mM Tris, 150mM NaCl (PH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
STORAGE of the Active Neuregulin 1 (NRG1)
Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months.
STABILITY of the Active Neuregulin 1 (NRG1)
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
