分子量
The recombinant rat IL20 consists of 153 amino acids and has a predicted molecular mass of 17.7 kDa. As a result of glycosylation, the apparent molecular mass of the recombinant protein is approximately 17 kDa in SDS-PAGE under reducing conditions.
缓冲液
Lyophilized from sterile PBS, 20% Glycerol, pH 7.4.
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Please refer to the specific buffer information in the hard copy of 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.

IL-20 背景信息

IL2/Interleukin-2 belongs to the IL-1 family. It is a cytokine structurally related to interleukin 1. IL2/Interleukin-2 can be detected in skin, trachea, and other tissues. It is produced by activated keratinocytes and monocytes and transmits an intracellular signal through two distinct cell-surface receptor complexes on keratinocytes and other epithelial cells.It has been shown that interleukin-2 transduce its signal through signal transducer and activator of transcription 3 (STAT3) in keratinocytes. It may be involved in epidermal function and psoriasis. It also regulates proliferation and differentiation of keratinocytes during inflammation, particularly inflammation associated with the skin. In addition, IL2/Interleukin-2 also causes cell expansion of multipotential hematopoietic progenitor cells. A specific receptor for this cytokine is found to be expressed in skin and upregulated dramatically in psoriatic skin, suggesting a role for this protein in epidermal function and psoriasis.
