Species : | Rhesus macaque |

Tag : | Non |
Protein Length : | 115 |
Description : | Through binding to the IL-5 receptor, IL-5 stimulates B cell growth and increases immunroglobulin secretion. It is also a key mediator in eosinophil activation. Interleukin-5 has long been associated with the cause of several allergic diseases including allergic rhinitis and asthma. IL-5 is a 115-amino acid (in rhesus macaque, 133 in the murine) -long TH2 cytokine that is part of the hematopoietic family. Unlike other members of this cytokine family (namely IL-3 and GM-CSF), this glycoprotein in its active form is a homodimer. |
Form : | Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH 7.4, with 5 % Trehalose. |
Bio-activity : | Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 5 ng/ml, corresponding to a specific activity of > 2.0 × 10⁵ IU/mg. |
Molecular Mass : | Approximately 26.1 kDa, a disulfide-linked homodimer of two 115 amino acid polypeptide chains. |
AA Sequence : | IPTEIPASALVKETLALLSTHRTLLIANETLRIPVPVHKNHQLCTEEIFQGIGTLESQTVQGGTVERLFKNLSLIKKYIGGQKKKCGEERRRVNQFLDYLQEFLGVMNTEWIIES |
Endotoxin : | Less than 0.1 EU/µg of rRhIL-5 as determined by LAL method. |
Purity : | >98% by SDS-PAGE and HPLC analysis. |
Storage : | Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution. |
Reconstitution : | We recommend that this vial be briefly 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. |
