一般描述

SIGMAFAST™蛋白酶抑制剂片剂是由多种蛋白质抑制剂混合而成的水溶性片剂，包括AEBSF、E-64、bestatin、leupeptin、aprotinin和EDTA。 一片可以配制100mL酶复合液，并可抑制20 g细胞提取物中的蛋白酶。
The use of SIGMAFAST Protease Inhibitor Tablets is not advised with HIS-Select® products or other immobilized metal affinity chromatography (IMAC) products. These tablets contain EDTA, which is a metal chelator and can potentially remove metal ions from these affinity products.

特异性

抑制丝氨酸、半胱氨酸、天冬氨酸和金属蛋白酶。

应用

这些 片剂针对常规用途进行了优化和测试。 它们可用于多种应用，包括 和冰冷放射免疫沉淀测试缓冲液一起收集气管残留物 以确定气管基础细胞命运（tracheal basal cell fate），并可使大鼠肺组织均质用于 蛋白免疫印迹分析。
SIGMAFAST Protease Inhibitor Tablets has been used:
  • to wash raw semen for membrane protein analysis
  • in a solution to incubate CD4+ T cells to obtain total cell lysates for western blot analyses
  • as a component of NP-40 buffer to homogenize the spinal cord tissue centered at the injury epicenter to conduct western blot analysis
  • as a component in radio-immunoprecipitation assay (RIPA) buffer to homogenize the spinal cord tissue centered at the injury center to detect neuregulin-1 beta 1 (Nrg-1ß1) in spinal cord tissue samples with enzyme-linked immunosorbent assay (ELISA)

特点和优势

  • 广谱蛋白酶抑制作用：抑制丝氨酸、半胱氨酸、天冬氨酸和金属蛋白酶，这使其成为各种应用中蛋白酶抑制的多功能解决方案。
  • 水溶性片剂形式：易于使用和制备，一片片剂可以制备100mL混合物。
  • 蛋白酶抑制剂混合物：提供全面有效的蛋白酶抑制解决方案。
  • 经过一般用途的测试和优化：经过各种应用验证的高性能和可靠性。
