The Recombinant Human IL-16 Protein is a biologically active recombinant protein that plays a significant role in various cellular processes and signaling pathways in human biology. This protein is widely employed in immunological research, cell biology studies, protein-protein interaction analyses, and therapeutic development, providing researchers with a reliable tool for investigating IL-16 function and its implications in health and disease.
This product (SKU: RPCB0168) is produced using E. coli and features a C-His tag for convenient detection and purification. The protein exhibits a calculated molecular weight of 14.09 kDa with an observed molecular weight of 20 kDa under denaturing conditions, achieving ≥ 95 % as determined by SDS-PAGE.. Functional bioactivity has been validated through rigorous quality control assays, confirming its suitability for demanding research applications.
High quality, high purity and low endotoxin recombinant Recombinant Human IL-16 Protein (RPCB0168), tested reactivity in E. coli and has been validated in SDS-PAGE.100% guaranteed.
Endotoxin:
< 0.1 EU/μg of the protein by LAL method.
Purity:
≥ 95 % as determined by SDS-PAGE.
Formulation:
Lyophilized from a 0.22 μm filtered solution of 20mM Tris, 150mM NaCl, pH 8.0.Contact us for customized product form or formulation.
Bio-Activity:
Measured by its binding ability in a functional ELISA. Immobilized Recombinant human IL16 at 5 μg/mL (100 μL/well) can bind Recombinant human CD4 with a linear range of 0.2-1 μg/mL.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
The protein is a pleiotropic cytokine that functions as a chemoattractant, a modulator of T cell activation, and an inhibitor of HIV replication. The biological activities ascribed to IL-16 are reported to be dependent on the cell surface expression of CD4, suggesting that IL-16 is a CD4 ligand. Besides its chemotactic properties, IL-16 has also been shown to suppress HIV-1 replication in vitro. Recombinant E. coli-derived IL-16 produced at is present mostly as a monomer, exhibits chemotactic activity for lymphocytes at high concentrations, lacks chemotactic activites for monocytes, and binds the extracellular domain of CD4 with low affinity.
Recombinant Human IL-16 Protein was determined by SDS-PAGE under reducing conditions with Coomassie Blue.
Immobilized Recombinant human IL16 at 5 μg/mL (100 μL/well) can bind Recombinant human CD4 with a linear range of 0.2-1 μg/mL.
