GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.Recombinant?Recombinant — produced via recombinant expression for defined sequence and consistency. Use for reproducible, animal-free proteins of known origin.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥95%(SDS-PAGE)See COA

Biochemical and Physiological Mechanisms
Neuregulin-2 (NRG2) is a novel member of the neuregulin family of growth and differentiation factors. Through interaction with the ErbB family of receptors, neuregulin-2 induces the growth and differentiation of epithelial, neuronal, glial and other types
Bioactivity
Measured in a cell proliferation assay using MCF-7 human breast cancer cell line. The ED50 for this effect is typically 9.6 ng/mL.
42.0-53.1 kDa, under reducing conditions; 41.7-51.0 kDa, under non-reducing conditions.
