| 日数 | Process |
| Day0 | 50ul pre-immune sera and 1st-immunization with CFA (Complete Freund's adjuvant) |
| Day21 | 2nd-immunization with IFA (Incomplete Freund's adjuvant) |
| Day35 | 3rd-immunizaiton with IFA |
| Day45 | serum collected for ELISA test |
| We will provide ELISA data and ELISA protocol to you by e-mail | |
| Process | |
| Day 50 | Strengthen-immunization for 2 mice with PBS |
| Day 54 | collection of positive serum and perform two hybridoma fusions based on highest antigen binding titer |
| Day 64-68 | ELISA test for cell culture supernatant and select positive clones; Identify positive antibodies' subtypes |
| Day 69-83 | Provide ELISA data to you for check and we will provide 200ul culture supernatants for each positive hybridoma's. We will keep 10-20 clones of ELISA positive and keep all the positive clones at most of 2 week for message delivery. |
| Day 84 | Make sure the hybridomas the client selected. |
| Day61 | 1st-subcloning |
| Day71 | ELISA test for cell supernant and select positive |
| Day72 | 2nd-subcloning |
| Day82 | ELISA test for cell supernant and select positive |
| Day83 | 3rd-subcloning |
| Day83-day84 | ELISA test for cell supernant and select positive |
| Day84-90 | Choose 1 subclone with the highest ELISA titer for each positive hybridoma |
| Day 91 | Injecting 2 mice with liquid paraffin for each clone |
| Day 91-98 | Cells expanding culture |
| Day99 | ELISA test for cell supernant; Identify all the clones still postive |
| Day92 | Injecting the hybridoma to mice intraperitoneally |
| Day100-106 | Collect ascites |
| Day107-114 | Antibody purification by protein A/G and ELISA test |
