Precision
Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
             
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of rat IL-13 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Materials provided
  • A micro ELISA plate --The 96-well plate has been pre-coated with an anti-rat IL-13 antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
  • Two vials lyophilized standard --Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
  • One vial Biotin-labeled IL-13 antibody (100 x concentrate) (120 μl/bottle) --Act as the detection antibody.
  • One vial HRP-avidin (100 x concentrate) (120 μl/bottle) --Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
  • One vial Biotin-antibody Diluent (15 ml/bottle) --Dilute the high concentration Biotin-antibody to an appropriate working solution.
  • One vial HRP-avidin Diluent (15 ml/bottle) --Dilute the high concentration HRP-avidin solution to an appropriate solution.
  • One vial Sample Diluent (50 ml/bottle)--Dilute the sample to an appropriate concentration.
  • One vial Wash Buffer (25 x concentrate) (20 ml/bottle) --- Wash away unbound or free substances.
  • One vial TMB Substrate (10 ml/bottle) --Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
  • One vial Stop Solution (10 ml/bottle) --Stop the color reaction. The solution color immediately turns from blue to yellow.
  • Four Adhesive Strips (For 96 wells) --Cover the microplate when incubation.
  • An instruction manual
Materials not provided
  • A microplate reader capable of measuring absorbance at 450 nm, with the correction wavelength set at 540 nm or 570 nm.
  • An incubator can provide stable incubation conditions up to 37°C±5°C.
  • Centrifuge
  • Vortex
  • Squirt bottle, manifold dispenser, or automated microplate washer
  • Absorbent paper for blotting the microtiter plate
  • 50-300ul multi-channel micropipette
  • Pipette tips
  • Single-channel micropipette with different ranges
  • 100ml and 500ml graduated cylinders
  • Deionized or distilled water
  • Timer
  • Test tubes for dilution

Target Background

Function
(From Uniprot)
Cytokine. 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.

  1. SUMF2 may mediate airway inflammation in allergic asthma by modulating the expression of IL-13 PMID: 26722390
  2. IL-13 significantly enhanced C/EBP-alpha/COX-2 expression and PGE2 production in LPS-treated microglial cells. Paradoxically, IL-13 abolished C/EBP-beta/PPAR-gamma/HO-1 expression. PMID: 23881867
  3. asthma the ERK expression and activation levels were increased, as was the protein level of IL-13. The ERK signaling pathway may be involved in the increased expression of the Th2 cytokine IL-13 in asthma. PMID: 20819635
  4. The IL-13 system is a novel regulator of paSMC growth. Dysregulation of IL-13 receptor expression in IPAH may partially underlie smooth muscle hypertrophy associated with pathological vascular remodeling in IPAH. PMID: 20522789
  5. IL-13 is involved in tobacco smoke-induced changes in the structure and function of rat intrapulmonary airways PMID: 19783789
  6. This finding provides an unequivocal evidence of IL-13 participation in pancreatic fibrosis, illustrating a new strategy for chronic pancreatitis. PMID: 20100461
  7. Inhibition of HO-1 with tin protoporphyrin reversed cytoprotective/antiapoptotic effects of IL-13 in liver transplantation. PMID: 12919086
  8. IL-13 may control brain inflammation by inducing the death of activated microglia in vivo, resulting in an enhancement of neuronal survival. PMID: 15042582
  9. study demonstrated at the protein and mRNA levels, both in vivo and in vitro, that alveolar macrophages produce IL-25 and IL-13 in response to fine particles of TiO2 PMID: 15961726
  10. IL-13 overexpression in the rat could lead to podocyte injury and minimal-change-like nephropathy. PMID: 17429054
  11. The findings support a role for IL-13 as an in vivo antiangiogenic factor and provide a rationale for its use in RA to control. pathologic neovascularization. PMID: 17665443
  12. IL-13 down-regulates the cytokine-induced iNOS transcription by decreasing iNOS specific IRF-1/ISRE binding activity PMID: 17723228
  13. expression decreased in lung in response to alcohol exposure PMID: 19120067
  14. Endogenous IL-13 triggers microglial NADPH oxidase-derived oxidative stress, leading to degeneration of hippocampal neurons in vivo. PMID: 19752235
