We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Target Background

Proinflammatory and angiogenic cytokine that may be involved in epidermal function and psoriasis. Angiogenic and proliferative activities are antagonized by IL10. May act through STAT3.
Gene References into Functions
  1. Authors demonstrated that ER(alpha), GATA3 and FOXA1 form a transcriptional complex with Ell3 to regulate IL-20 expression in ER(+) breast cancer cells. FOXA1 represses IL-20 expression, whereas GATA3 and ER(alpha) activate it. PMID: 28514748

  14. We observed that IL-20 which is an IL-10 group angiogenesis indicator was suppressed in systemic sclerosis, suggesting abnormal angiogenesis. PMID: 23812620
  15. This study demonstrates that rs1713239 and infection may have potential synergetic effect on modulating the transcriptional activity of IL-20. PMID: 23892591
  16. The mRNA levels of p40, IL-20 and IL-21 at baseline may serve as potential predictors of treatment response to ustekinumab treatment in psoriasis. PMID: 22930279
  17. IL-10-- and IL-20--expressing epithelial and inflammatory cells are increased in patients with ulcerative colitis. PMID: 23207823
  18. the GG genotypes of the IL-20 polymorphisms (rs2981573 and rs2232360) might have an important role in the development of UC in the Mexican population. PMID: 23183096
  19. A blood test for discrimination of patients with acute cellular rejection from transplanted kidney is based on simultaneous quantification of three analytes: IL-1 receptor antagonist, IL-20 and soluble CD40 ligand. PMID: 22948742
  20. Interleukin-20 promotes migration of bladder cancer cells through extracellular signal-regulated kinase (ERK)-mediated MMP-9 protein expression leading to nuclear factor (NF-kappaB) activation by inducing the up-regulation of p21(WAF1) protein expression PMID: 23271730
