Epigen (Human, Recombinant, Highly Pure) – Catalog Number: B2010277 (10 ug)

Epigen (Human, Recombinant) is provided as a lyophilized powder with a defined 10 ug fill (Catalog B2010277) and a listed pH of 7.4 upon reconstitution. The supplier describes this CHO-expressed protein as an EGF-like growth factor with mitogenic effects on cells expressing ErbB-1, aligning it with research that explores epidermal growth factor receptor signaling. The concise specification set—amount, supplied form, reconstitution pH, storage, keywords, and biotechnology-grade note—supports clean SOP inclusion, LIMS mapping, and inventory traceability in multi-user labs.

Within research workflows, recombinant epigen can be incorporated into qualitative studies that examine receptor-dependent responses or pathway activation in cell systems known to express ErbB-1. Because the listing does not prescribe a working concentration or buffer additives beyond reconstitution to pH 7.4, a practical approach is to titrate the protein in small pilot experiments tailored to the matrix and readout being used, such as general proliferation measurements or downstream marker assessments. Documenting buffer composition, incubation time and temperature, and time-at-temperature during handling helps establish a reproducible operating window and simplifies method transfer between analysts and instruments. The lyophilized format facilitates precise aliquoting, and storage at −20 °C supports routine cold-chain practices.

Typical use cases include assembling qualitative receptor-ligand engagements for pathway demonstrations, creating platform checks where a defined growth factor input is required, and building training exercises focused on handling lyophilized cytokine-like reagents. The biotechnology-grade statement (minimum 95% purity; solutions prepared with Type I ultrapure water and filtered) aligns with expectations for low background during optimization. Staying within research-only boundaries, this epigen offering provides a clearly specified, documentation-friendly component for laboratories standardizing ErbB-1–relevant exploratory work.

Why researchers choose this product:

• CHO-expressed recombinant human epigen listed as an EGF-like growth factor
• Supplier notes mitogenic effects on cells expressing ErbB-1
• Lyophilized powder with pH 7.4 upon reconstitution for consistent handling
• Specified storage at −20 °C fits routine cold-chain workflows
• Biotechnology-grade (minimum 95%) with documentation-ready fields and keywords
