Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
Protein bands: 10kDa, 14kDa, 18kDa, 22kDa, 26kDa, 33kDa, 44kDa and 70kDa.
Double intensity bands: The 26kDa, 18kDa, 10kDa bands are at double intensity to make location and size approximation of proteins of interest quick and easy.
热休克蛋白40(HSP40)重组蛋白Ready-to-use: No need to heat, dilute or add reducing agents before use.

文献和实验Peptide substrate identification for yeast Hsp40 Ydj1 by screening the phage display library
We have identified a peptide substrate for molecular chaperone Hsp40 Ydj1 by utilizing the combination of phage display library screening and isothemol titration calirimetry (ITC). The initial peptide substrate screening for Hsp40 Ydj
体 对于包涵体的纯化，包涵体的前处理是很重要的。 包涵体中主要含有重组蛋白,但也含有一些细菌成分,如一些外膜蛋白、质粒DNA和其它杂质。洗涤常用1%以下的中性去垢剂，如Tween、Triton、Lubel和 NP40等加EDTA和还原剂2-巯基苏糖醇（DTT）、β-巯基乙醇等反复多次进行，因去垢剂洗涤能力随溶液离子强度升高而加强，在洗涤包涵体时可加50 mM NaCL。这样提取的包涵体纯度至少可达50%以上，而且可保持元结构。也可用低浓度的盐酸胍或尿素/中性去垢剂/EDTA/还原剂等洗去
裂解细胞。其中超声波裂解细胞是更广泛应用的一种方法，但利用此方法细胞的裂解率较低，并且液不适用于大量细胞的裂解（超出 50 g）。无论选择何种方法，都必须将细胞置于冰上； 4) 细胞裂解后在混和液中迅速加入蛋白酶抑制剂，每 40 mL 混和液加入 5 mL 的含有 EDTA 的蛋白酶抑制剂 Cocktail Set II 或 1mL 的蛋白酶抑制剂 Cocktail Set III（选做）； 5) 10000
