一般說明

二肽基肽酶IV(DPP IV)是一种二聚II型膜内在糖蛋白,属于脯氨酰特异性蛋白酶家族的成员。它在上皮组织和非上皮组织中大量表达。它在肾脏和结肠中高度表达。[1]

生化/生理作用

二肽基肽酶IV(DPP IV)可控制胰岛素刺激激素、胰高血糖素样肽(GLP-1)以及葡萄糖依赖性促胰岛素多肽(GIP)等。它作为治疗II型糖尿病(T2DM)的治疗靶点前景可观。′[2]除了催化作用之外,DPP-4还可用作结合蛋白和细胞外蛋白因子的配体。[3]DPP-4抑制使GLP-1和GIP的活性延长,因此,DPP-4抑制剂有助于维持葡萄糖的稳态。与早期口服降血糖药物相比,DPP IV抑制剂可延长血糖控制的时间。[4]

The proline-specific dipeptidyl aminopeptidase IV (DPP IV, DPP-4, CD26), widely expressed in mammalians, releases X-Pro/Ala dipeptides from the N-terminus of peptides. DPP IV is responsible of the degradation of the incretin peptide hormones regulating blood glucose levels. Several families of

Questions

1–2 of 2 Questions  
  1. Would our lab be able to store this product at -80 degrees celsius without compromising its composition? 

    1 answer
    1. It is recommended to store this product at -20°C. The long term stability of this product at -80°C has not been determined. However, there are no issues anticipated by storing this material at ultra-low temperatures.

      Helpful?

  2. What is the concentration of this product and what is the working concentration suggested? Thanks!

    1 answer
    1. This product as provided at a concentration of 4 mM. The working concentration recommendations are 10 μl/mL of whole blood or 20 μl/mL of buffer, plasma, serum, or tissue culture medium. These are general usage recommendations, the optimal concentration is application- and/or system-dependent. The final working concentration should be empirically determined by the end user.
