The invention provides a kit for screening protein crystals by taking salt as a precipitator. The kit comprises a buffer solution, a precipitator and an additive, wherein the salt with relatively high crystallization efficiency is selected as the precipitator in the crystal kit; and meanwhile, a few of additive molecules are added to improve the solubility and stability of the protein, so as to obtain relatively high screening efficiency. By adopting the kit, the success rate of screening of protein crystallization conditions can be effectively improved. |
