Recombinant Human Interleukin-4 (IL-4) Protein

Catalog Number: PRP1912

English Name: Human IL-4 Protein

Product Overview

Recombinant Human IL-4 cytokine is a high-purity protein expressed in E. coli, tag-free, and possesses natural biological activity. This protein is suitable for cell culture and related immunological research, supporting Th2 cell differentiation and exploration of inflammation and immune regulation mechanisms.

Product Characteristics

• Sequence Source: Human IL-4 (His25-Ser153), UniProt ID: P05112-1
• Molecular Weight: Approximately 15.1 kDa
• Protein Length: 129 amino acids
• Expression Host: Escherichia coli (E. coli)
• Purity: >98% (as determined by SDS-PAGE)
• Activity (ED₅₀): 0.5308 ng/mL (TF-1 cell proliferation assay)
• Endotoxin: <1 EU/μg (LAL method)

Product Formulation and Storage

This product is supplied as a liquid in a buffer containing 20 mM Tris-HCl, 150 mM NaCl, 10% glycerol, pH 8.0. It is recommended to store at -20°C and avoid repeated freeze-thaw cycles. After dilution, aliquoting and storage at -20°C or -80°C is advised.

Application Suggestions

Suitable for cell proliferation, differentiation, and signal transduction studies. It is recommended to dilute the protein in a buffer containing a carrier protein (e.g., 0.1% HSA or BSA) to maintain stability.
