This sandwich kit is for the accurate quantitative detection of Chicken Super Oxide Dimutase (also known as SOD) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.
This kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with Chicken SOD antibody. SOD present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Chicken SOD Antibody is added and binds to SOD in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated SOD antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Chicken SOD. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.
Serum Allow serum to clot for 10-20 minutes at room temperature. Centrifuge at 2000-3000 RPM for 20 minutes.
Plasma Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 15 minutes at 2000-3000 RPM at 2 - 8°C within 30 minutes of collection.
Urine Collect by sterile tube. Centrifuge at 2000-3000 RPM for approximately 20 minutes. When collecting pleuroperitoneal fluid and cerebrospinal fluid, please follow the procedures above-mentioned.
Cell Culture Supernatant Collect by sterile tubes when examining secrete components. Centrifuge at 2000-3000 RPM for approximately 20 minutes. Collect the supernatants carefully. When examining the components within the cell, use PBS (pH 7.2-7.4) to dilute cell suspeion to the cell concentration of approximately 1 millioml. Damage cells through repeated freeze-thaw cycles to let out the iide components. Centrifuge at 2000-3000 RPM for approximately 20 minutes.
Tissue Rie tissues in PBS (pH 7.4) to remove excess blood thoroughly and weigh before homogenization. Mince tissues and homogenize them in PBS (pH7.4) with a glass homogenizer on ice. Thaw at 2-8°C or freeze at -20°C. Centrifuge at 2000-3000 RPM for approximately 20 minutes.
All reagents should be brought to room temperature before use.
Standard Recotitute the 120μl of the standard (960U/L) with 120μl of standard diluent to generate a 480ng/ml standard stock solution. Allow the standard to sit for 15 mi with gentle agitation prior to making dilutio. Prepare duplicate standard points by serially diluting the standard stock solution (480U/L) 1:2 with standard diluent to produce 240ng/ml, 120U/L, 60U/L and 30U/L solutio. Standard diluent serves as the zero standard(0 U/L). Any remaining solution should be frozen at -20°C and used within one month. Dilution of standard solutio suggested are as follows:
