Recombinant Human IL16

Cat.No.: IL16-503H
Product Overview: Recombinant Human IL16 produced in E. coli is approximately 12.4 kDa, a single non-glycosylated polypeptide chain containing 121 amino acids.
Description: Human Interleukin-16 (IL-16) is also called lymphocyte chemoattractant factor (LCF) and it has thre isoforms which are cleaved from pre-Interleukin-16. IL-16 is mostly secreted by lymphocytes, epithelial cells, eosinophils, and CD8+ T cells. It has many functions including induction of the IL-2Rα on T cells, suppression of human immunodeficiency virus (HIV) replication, inhibition of T-cell antigen receptor/CD3 mediated T-cell stimulation in mixed lymphocyte reactions and so on. It signals through CD4 receptor. Furthermore, recombinant human IL-16 (121 a.a.) contains 121 amino acid residues and it shares 85 % a.a. sequence identity with murine IL-16.
Source: E. coli
Species: Human
Form: Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
Bio-activity: Fully biologically active when compared to standard. The biologically active determined by a chemotaxis bioassay using human peripheral T Lymphocytes is in a concentration range of 50-500 ng/ml.
Molecular Mass: 12.4 kDa
AA Sequence: SAASASAASD VSVESTAEAT VCTVTLEKMS AGLGFSLEGG KGSLHGDKPL TINRIFKGAA SEQSETVQPG DEILQLGGTA MQGLTRFEAW NIIKALPDGP VTIVIRRKSL QSKETTAAGD S
Endotoxin: Less than 1EU/μg of rHuIL-16, 121 a.a. as determined by LAL method.
Purity: >95% by SDS-PAGE and HPLC analyses.
Usage: This material is for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
Storage: This lyophilized preparation is stable at 2-8 centigrade, but should be kept at -20 centigrade for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 centigrade. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 centigrade to -70 centigrade. Avoid repeated freeze/thaw cycles.
Reconstitution: We recommend that this vial be briefy centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 centigrade. Further dilutions should be made in appropriate buffered solutions.
