Definitions
- MASP-2 When MBL binds to pathogens, MASP-2 is activated, cleaving complement components C4 and C2 into C4a, C4b, C2a, and C2b, generating C3 convertase C4bC2b, followed by C3 being converted to C3b by C4bC2b, and finally forming a membrane attack complex (MAC) after C5 is converted to C5b by C3b.

- Example 1 Generation of human, mouse, and cynomolgus monkey MASP-2 antigens
- the above MASP-2 expression constructs were transfected into ExpiCHO-s cells using the ExpiFectamine CHO transfection kit.
- ExpiCHO-s cells were cultured in serum-free ExpiCHO expression medium. 14 days after transfection, the supernatant was collected. After centrifugation and filtration, the supernatant was loaded onto an anti-FLAG or anti-HIS column and then purified using the GE AKTA purification system. After washing, the MASP-2 protein was eluted with citric acid (pH 3.5) for animal immunization.
- mice or rats were immunized with DNA expressing the chimeric MASP-2 antigen described above via the Helios gene gun system (Bio-Rad). Immunized animals were boosted with recombinant MASP-2 protein every two weeks. Four days after the last boost immunization, the animals were sacrificed for hybridoma fusion. Spleen cells were isolated and fused with SP2-0 cells via an electrofusion method. The resulting hybridoma cells were cultured in DMEM medium containing hypoxanthine-aminopterin-thymidine.
- the hybridoma supernatant was collected for antigen binding screening.
- the full-length human MASP-2 protein was coated in an ELISA plate at a concentration of 0.5 ⁇ g/ml, 100 ⁇ l per well. After blocking with PBS containing 1% BSA + 1% normal goat serum + 0.05% Tween20, the hybridoma supernatant was added to the plate for 1 hour. The specific binding of the hybridoma antibody to human MASP-2 was detected with an anti-mouse antibody linked to horseradish peroxidase (HRP). The positive clones that bound to ELISA were selected for further activity screening.

Dialysis is performed three times, with durations of 4 hours, 4 hours and overnight, respectively, and the stirring speed is 200 rpm.
- Slide-A-Lyzer dialysis cards can also be used for dialysis. Use a syringe with a needle to load 3-12 ml of sample into the dialysis card, immerse it in 100 to 200 times the target buffer, and dialyze the dialysis card three times at room temperature with stirring at 300 rpm, for 4 hours, 4 hours and overnight, respectively.

Dilute the sample to 4 mg/mL with the corresponding buffer, take 100 ⁇ L and add it to a 96-well plate, centrifuge at 3000 rpm for 5 min, add 10 ⁇ L of silicone oil to cover the sample, and centrifuge at 3000 rpm for 5 min. The instrument performs linear heating at 1°C/min in the range of 25-80°C, and a single sample is measured 8 times, with each acquisition time of 3s.

The sample does not need to be diluted and 1 mL is directly injected using a pipette. The number of particles in the range of ⁇ 2 ⁇ m, ⁇ 10 ⁇ m, and ⁇ 25 ⁇ m per mL of sample is reported.
- Whole-column imaging capillary isoelectric focusing (icIEF): The sample is mixed with an appropriate mixture containing pl markers and amphoteric electrolytes and then enters the FC-coated capillary of the iCE3 system through an autosampler. After the high voltage separation step, the different charge isomers of the protein migrate to their respective isoelectric point positions, and then the positions determined after separation are captured by the UV detector (UV absorption spectrum collected at UV280nm by a CCD camera with full column detection). Using the iCE system software, the isoelectric point of the sample peak is calibrated by the focusing position of the sample peak and the corresponding pl marker, and subsequent data analysis is performed in the Empower software.

- the SEC HMW% content of proteins in the histidine formulation was generally small, and the SEC HMW% content of proteins in the acetic acid formulation and the citric acid formulation increased with increasing pH, and the SEC HMW% of F14 (Ace5.5) increased to a greater extent.
- the stability of the acetic acid and histidine systems is better.
- the pH 4.5 and pH 5.0 in the acetic acid system, and the pH 5.0 and pH 5.5 in the histidine system have good stability for proteins.
- the acetate buffer system has good buffering capacity and robustness at pH 5.0 and the histidine system has good buffering capacity and robustness at pH 5.5, there is a good operating space when adjusting the pH in the process, and there is better risk control for extreme situations that deviate from the target value.
- the use of histidine is less irritating and has higher patient tolerance. Therefore, F13 (Ace5.0) acetate buffer pH 5.0 and F16 (His5.5) histidine buffer pH 5.5 are preferred buffer systems.
- the sample prescription information and test method are shown in Table 33.
- the sample was replaced by dialysis into the target prescription buffer, then diluted to 20 mg/mL with the corresponding excipient stock solution, and finally filtered with a 0.22 ⁇ m PVDF membrane.

- the particle size and PD% results there was no significant difference under stability conditions except 40°C; because 40°C is a more severe stress condition for protein preparations, it is normal for the results to change significantly, and the specific judgment should be based on the results of SEC, NR-CE, and CEX.
- ND means not detected
- the results of the low-concentration formula confirmation experiment showed that the final formula F21 can maintain long-term stability at 5°C, 25°C, -20°C, and -30°C, has good tolerance to freezing, thawing, and shaking, does not change under light and stirring conditions, and will change to a certain extent under 40°C, so the sample should be prevented from being placed at high temperature for a long time.
- the development of low-concentration preparations has undergone surfactant screening, excipient screening, pH screening, and final formula confirmation research, and the final low-concentration preparation formula was selected as 20mg/mL protein, 10mM histidine salt, 8.6% (w/v) sucrose, 0.05% (w/v) polysorbate 80, and pH 5.3.

- a positive kD indicates that the interaction between protein molecules in the system is a strong net repulsive force, which is beneficial to the long-term colloidal stability of the protein.
- the kD is negative, it indicates that the interaction between protein molecules is a net attractive force, which is not conducive to the long-term colloidal stability of the protein.
- Tonset can predict the thermal stability of proteins. Except for the F29 (ARG) arginine formulation, the Tonset values of all samples were greater than 60°C, indicating that in these formulations, the proteins had good thermal stability.

- the kD and Tonset of arginine are inferior to those of sucrose and proline.
- the buffer system using histidine is less irritating to injection, and the pH should not be too low. Therefore, on the whole, 10mM Acetate, pH 5.0, 10mM Histidine, pH 5.0, and 10mM Histidine, pH 5.5 are preferred, and sucrose or proline are used for the next step of research.

It will change under light and stirring conditions, and the change is greater under 40°C, so the sample should be protected from long-term light, high temperature and vigorous stirring.
