Time Line |
Phase I: Immunogen preparation |
- Peptide synthesis: 5 mg of phospho-peptide (up to 15 residues) with >90% purity and 3 mg non-phospho-peptide with >70% purity is synthesized by GenScript. 2 mg of phospho-peptide and 2 mg of non-phospho-peptide will be delivered to the customer along with the final antibody product.
- Conjugation: The modified peptide is conjugated to the carrier protein KLH.

28 days |
Phase II: Immunization and cell fusion with MonoExpress™ protocol |
- Immunization: Balb/c mice or rats are immunized and boosted with MonoExpress™ immunization protocol.
- Fusion: Electrofusion is performed and at least 10,000 clones can be obtained from each fusion. Additional fusions are available to reach our guarantee without extra charge.
|
45 days |
Phase III: Screening and supernatant samples preparation for 1st delivery |
- Screening and isotyping: The hybridoma cells are screened by ELISA with phospho and non-phospho peptides and all positive clones are expanded into 24-well plates. Up to 5 clones with the best ELISA value and specificity to phospho-peptide are selected for isotyping.
- 1st delivery: 2 ml supernatant samples for each clone are prepared for 1st delivery. Antibody Certificate of Analysis report is prepared with ELISA data and IgG concentration for each sample.
|
Phase IV: Subcloning, expansion, cryopreservation, antibody production and final delivery |
- Subcloning, expansion and cryopreservation: Up to 5 clones are subcloned by limiting dilution, expanded and frozen.
- Antibody production: At least 2 mg purified antibody is produced for the clone with best screening result. The cross reactivity with non-phospho peptide < 10% for the purified antibody.
- Final Delivery: Two vials of cell culture for each cell line, at least 2 mg qualified purified antibody, 2 mg of unconjugated phospho-peptide and 2 mg of non-phospho peptide are delivered to the customer.
