Product Overview

This product is recombinant human IL‑16 produced in an animal‑free expression system and bearing a His‑tag, suitable for cell‑culture and related research applications. The protein is expressed in Escherichia coli, exhibits high purity (>95%) and low endotoxin level (<0.1 EU/µg), meeting stringent experimental requirements.

Product Characteristics

• Source: Human (Homo sapiens)
• Expression Host: Escherichia coli expression system
• Molecular Weight: approximately 18 kDa
• Purity: >95% (SDS‑PAGE analysis)
• Endotoxin Level: <0.1 EU/µg (LAL assay)
• Product Form: Lyophilized powder (lyophilization buffer: sterile PBS, pH 8.0)

Applications

The recombinant protein is suitable for chemotaxis studies, T‑cell activation modulation assays, and related immunological research.

Usage Recommendations

Prior to use, centrifuge the vial. Reconstitute with the supplied re‑solubilization buffer to a concentration of at least 100 µg/mL. Further dilutions can be performed as required. It is advisable to dilute in a buffer containing a carrier protein (e.g., 0.1 % BSA, 10 % FBS, or 5 % HSA) to enhance protein stability.

Storage and Shipping

• Storage Conditions: Lyophilized powder stable at –20 °C for 1 year; reconstituted solution stable at 2–8 °C for 1 week; aliquoted dilutions stable at –20 °C or –80 °C for 3–6 months
• Shipping Conditions: Shipped on ice packs (blue ice)

Background

Interleukin‑16 (IL‑16), also known as lymphocyte‑chemoattractant factor (LCF), is a pleiotropic cytokine that participates in T‑cell chemotaxis, activation regulation, and inhibition of HIV replication. Its signaling is mediated through the CD4 receptor.

Precautions

This product is for research use only and is not intended for human or clinical diagnostic applications. Please read the product manual before use and adhere to relevant laboratory safety guidelines.
