| 1. |
Put 100 ㎕ of capture antibody diluted with coating solution4 into each well (250ng/well). |
| 2. |
Following incubation for 2 hours at 37℃ (or overnight at 4 ℃ ) , pour out the coating solution. |
| 3. |
Put 300 ㎕ blocking solution5 into each well. |
| 4. |
Following incubation for 0.5 ~ 1 hour at 37℃ (or overnight at 4 ℃ ) , pour out the blocking solution. |
| 5. |
After washing out with 300 ㎕ of TBS-T buffer6, completely dry out the remaining solution by patting softly on paper towel. |
| 6. |
Put 100 ㎕ of titrated antigen solution (diluted with blocking buffer of 3% BSA/PBS) into each well and incubate in high humidity for 2 hours at room temperature. |
| 7. |
Pour out the antigen solution and wash out with 300 ㎕ of PBS (repeat 4 times). |
| 8. |
Put 100 ㎕ diluted primary antibody into each well and incubate for 1 hour at 37℃. |
| 9. |
After pouring out the plate, completely dry out the remaining solution by patting softly on paper towel. |
| 10. |
After washing out each well with 300 ㎕ of TBS-T buffer, completely dry out the remaining solution. Repeat these procedures three times. |
| 11. |
Put 100 ㎕ of enzyme-labeled secondary antibody and incubate for 1 hour at 37℃. |
| 12. |
After pouring out the plate, completely dry out the remaining solution by patting softly on paper towel. |
| 13. |
