Biological Activity
For determination of proliferative and cytokine responses, lymph node and spleen cells are collected 21 days after immunization and are stimulated in culture with the appropriate antigen. Cells of C57BL/6 mice and 129/J mice immunized with IRBP (1-20), human TFA proliferated in response to the peptide[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:C57BL/6 (H-2b) mice, H-2b (C57BL/6, 129/J) mice[2]
-
Dosage:200, 300 μg
-
Administration:I.h.; After 21 days
-
Result:C57BL/6 (H-2b) mice immunized with the human peptide (200-300 μg= 80-120 nmoles) developed EAU. 129/J mice (H-2b) also developed disease, albeit with a lower average score than C57BL/6.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
