Recombinant
Greater than 95 % by SDS-PAGE gel analyses
WB, ELISA
Beschränkungen
Nur für Forschungszwecke einsetzbar
Format
Lyophilized
Rekonstitution
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
Buffer
Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.
Lagerung
4 °C,-80 °C
Informationen zur Lagerung
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
IL13, IL-13, interleukin 13, NC30, P600, ALRH, BHR1, MGC116786, MGC116788, MGC116789,Interleukin-13 (IL-13) is a monomeric 17 kDa immunoregulatory cytokine that plays a key role in the pathogenesis of allergy, cancer, and tissue fibrosis. It is secreted by several helper T cell subsets, NK cells, mast cells, eosinophils, basophils, and visceral smooth muscle cells. Inhibits inflammatory cytokine production. Synergizes with IL2 in regulating interferon-gamma synthesis. May be critical in regulating inflammatory and immune responses. Positively regulates IL31RA expression in macrophages (By similarity).
Molekulargewicht
15.3 kDa. Due to glycosylation, the protein migrates to 15 kDa and 35-45 kDa based on Tris-Bis PAGE result.
