General description

用于标准应用。

Application

牛血清白蛋白组分 V 适用于标准应用，例如：
  • 稳定剂，可防止酶和其它蛋白质的蛋白水解和变性，特别是当蛋白质以低浓度存在时。
  • 免疫化学、生物化学、细胞生物学或分子生物学中的缓冲液成分
  • 还原剂
  • 用于 ELISA、Southern 印迹和蛋白质印迹中饱和蛋白质结合位点的蛋白质阻断剂
  • 需要添加蛋白质的培养基的补充剂
  • 载体蛋白
  • 凝胶电泳和蛋白质测定中的标准蛋白质

Preparation Note

储存条件（工作液）：在溶液中，白蛋白在 -15 至 -25 °C 下可稳定保存约三个月。

Southwestern blotting is used to investigate DNA-protein interactions. The advantage of this technique over other related methods such as electrophoretic mobility shift assay (EMSA) and DNA footprinting is that it provides information regarding the molecular weight of unknown protein factor.

Test and evaluation of engineered biothreat agent detection systems ("biodetectors") are a challenging task for government agencies and industries involved in biosecurity and biodefense programs. In addition to user friendly features, biodetectors need to perform both highly sensitive and specific

Cytokines like interferon (IFN)-γ, interleukin (IL)-2, IL-6, IL-10, and IL-12p40 are important biomarkers for characterizing the nature and strength of immune responses. It is important to be able to quantify the cytokines at the protein level in biological samples. Quantification
