In the process of antibody preparation, there is a common problem, that is, the antibody produced by host immunity reacts with the original specificity of immunity, but when it is applied to Western blot / IP / IHC / if, the negative experimental results often appear, which wastes precious time and money. This regret mainly comes from the unreasonable design of antigens. According to the current level of antibody preparation technology, the best way is to improve the specificity of antigens. We will analyze the properties of antigen molecules to design antigens with the best immunogenicity and provide you with higher quality antibodies.
