Then there is the target itself, a set of smaller molecules called haptens that are attached to the carrier.

然后是与载体结合的靶物质本身，他们是一组叫做半抗原的较小的分子。

Finally, there is a chemical cocktail called an adjuvant that helps get the immune system to pay attention to the carrier protein and the haptens.

最后，有一种叫做佐药的鸡尾酒帮助免疫系统对载体蛋白和半抗原做出反应。

Once built, they attached the new hapten molecules to carrier proteins, mixed them with adjuvant, injected the results into mice and waited.

一旦构建完成，他们把这些新的半抗原分子结合到载体蛋白上，并与佐药混合，注射进小鼠体内，等待结果。

They used computer models to visualise the haptens in three dimensions and thus work out how the molecules could be rearranged such that they could not spring, twist or turn when being examined by the immune system.

他们利用电脑模型来展现三维半抗原并解决了分子重新排布的问题，使他们在免疫系统检查时无法弹出，扭曲，旋转。
