Description générale

NBT is a chromogenic and soluble substance. It is a substrate of alkaline phosphatase (AP) and is converted to an indigo/purple dye on its action.

Application

  • Immunohistocytochemistry
  • Western blot
  • Southern blot
  • Northern blot
  • Colony and plaque hybridization
  • In situ hybridization

Forme physique

Solution (100 mg/ml) in 70% dimethylformamide (DMF) (v/v). The color of the NBT solution can vary between yellow and brown depending on the lot used.

Note: The color does not impair the quality or the function of the reagent. In some cases a precipitate may occur which is easily brought into solution by briefly warming the substrate at 37 °C.

Notes préparatoires

Working solution: Preparation of staining solution
  • Always prepare this solution fresh shortly before use!For all applications except DIG System: Add 50 μl NBT solution and 37,5 μl BCIP to 10 ml 0.1 M Tris-HCl, pH 9.5 (20 °C), 0.1 M NaCl, 0.05 M MgCl2.
  • For DIG System applications: Add 50 μl NBT solution and 37,5 μl BCIP to 10 ml 0.1 M Tris-HCl, pH 9.5 (20 °C), 0.1 M NaCl
  • Note: Do not include MgCl2 in the DIG detection buffer as this might lead to spotty background on the membrane after the detection procedure. Alkaline Phosphatase does not require Mg2+.

The regulation of gene expression is mediated at the transcriptional level by enhancer regions that are bound by sequence-specific transcription factors (TFs). Recent studies have shown that the in vivo binding sites of single TFs differ between developmental or cellular

The long-standing doctrine regarding the functional organization of the direct dorsal column (DDC) pathway is the "somatotopic map" model, which suggests that somatosensory afferents are primarily organized by receptive field instead of modality.

Although both uveal (UM) and cutaneous (CM) melanoma cells derive from the transformed melanocytes, their biology varies significantly in several aspects. Malignant transformation is frequently associated with alternations in cell glycosylation, in particular those concerning branched complex-type N-glycans. These changes
