产品介绍

纯度

≥ 95 % as determined by SDS-PAGE.

内毒素

< 20 EU per mg protein.

生物活性

1. Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED₅₀ for this effect is typically 0.5-5 ng/mL.
2. Labeled biotin to IL-15 Protein, Human, Recombinant by a certain molar ratio; Using the Octet RED System, the affinity constant (Kd) of IL-15 Protein, Human, Recombinant, Biotinylated (Cat. 10360-HNCE) bound to Anti-IL15 Antibody was 0.1nM. (Routinely tested)
3.Recombinant Human IL-2R beta/CD122 Protein, hFc Tag (Cat. No. 10696-H02H) captured on Protein A chip can bind Recombinant Human IL-15 Protein (Cat. No. 10360-HNCE) with an affinity constant of 4.48 nM as determined in an SPR assay (Biacore 8K) (Routinely tested).

The recombinant human IL15 consists of 114 amino acids and predicts a molecular mass of 12.8 kDa.

缓冲液

Lyophilized from sterile 50 mM Tris, 200 mM NaCl, pH 8.0.
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

Please refer to the specific buffer information in the hardcopy of datasheet or the lot-specific COA.

运输方式

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

稳定性 & 储存条件

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

IL-15 背景信息

The protein encoded by the IL15 gene is a cytokine that regulates T and natural killer cell activation and proliferation. This cytokine and interleukine 2 share many biological activities. They are found to bind common hematopoietic receptor subunits and may compete for the same receptor, and thus negatively regulate each other's activity. The number of CD8+ memory cells is shown to be controlled by a balance between this cytokine and IL2. This cytokine induces the activation of JAK kinases, as well as the phosphorylation and activation of transcription activators STAT3, STAT5, and STAT6. Studies of the mouse counterpart suggested that this cytokine may increase the expression of apoptosis inhibitor BCL2L1/BCL-x(L), possibly through the transcription activation activity of STAT6, and thus prevent apoptosis. Alternatively, spliced transcript variants of this gene have been reported.
