Mouse IFN-γ ELISPOT Pair 产品介绍
The enzyme-linked immunospot (ELISPOT) assay is a powerful tool for detecting and enumerating individual cells that secrete a particular protein in vitro. Based on the sandwich ELISA, the ELISPOT assay derives its specificity and sensitivity by employing high affinity capture and detection antibodies and enzyme-amplification. Although originally developed for analyzing specific antibody-secreting cells, the assay has been adapted for measuring the frequencies of cells that produce and secrete other effector molecules, such as cytokines. The sensitivity of the assay lends itself to measurement of even very low frequencies of cytokine producing cells (e.g., 1/300,000). Unique strengths of the assay include high sensitivity, high throughput, high content analysis, minimal volume of biological material required, applicability to frozen/thawed biological samples, and compatibility with other assays. For example, cells analyzed by ELISPOT can be transferred for cloning, proliferation assays, flow cytometry, or other methods of analysis.
This product contains sufficient reagents for five 96-well plates, including unlabelled anti-cytokine capture antibody (no azide/low endotoxin format), biotinylated anti-cytokine detection antibody and a Certificate of Analysis that provides lot-specific optimal reagent concentrations.

Mouse IFN-γ ELISPOT 对的推荐使用步骤
A. BD™ ELISPOT Streptavidin Horseradish Peroxidase (Cat. No. 557630) is recommended.
B. Coating Buffer (1X Phosphate Buffered Saline : 8 g NaCl; 0.2 g KCl; 1.44 g Na2HPO4-7H2O, 0.24 gKH2PO4; dissolved in H2O to a final volume of 1 liter. Adjust pH to 7.2, sterile-filter (0.2 μm-sized pore filter) and store at 4°C.
C. Blocking Solution: complete tissue culture medium (e.g. RPMI 1640 containing 10% Fetal Bovine Serum [FBS] and 1% Penicillin-Streptomycin.L-Glutamine [Gibco-BRL No. 10378-016]).
D. Wash Buffer I: 1X PBS containing 0.05% Tween-20 (0.5 mL Tween-20 per 1 L PBS).
E. Wash Buffer II: 1X PBS
F. Dilution Buffer: 1X PBS containing 10% FBS.
G. BD™ ELISPOT AEC Substrate Set (Cat. No. 551951) is recommended. Alternatively, Prepare as follows:
1. Prepare AEC (3-Amino-9-ethyl-carbazole; Sigma A-5754) stock solution: mix 100 mg AEC in 10 mL DMF (N,NDimethylformamide; Sigma D-4551). Caution: dispense DMF in fume hood. Store solution in glassware.
2. Prepare 0.1 M Acetate Solution: add 148 mL of 0.2 M acetic acid/glacial acidic acid to 352 mL of 0.2 M sodium acetate. Adjust volume to 1L DI water; adjust pH to 5.0.
3. For Final Substrate Solution, add 333.3 μL of AEC stock solution to 10 mL 0.1 M Acetate Solution. Filter through 0.45 μm filter. Add 5 μLof H 202 (30%) and use immediately.
