Descrição geral

Streptavidin is covalently coupled to alkaline phosphatase (AP) for the preparation of streptavidin-AP-conjugate.

Alkaline Phosphatase
Alkaline Phosphatase is often used as a label in enzyme immunoassays. AP converts the sensitive substrate X-phosphate/NBT into a stable, water soluble product.

Aplicação

Streptavidin-AP has been used to detect biotinylated compounds using:
  • ELISA
  • Immunohistocytochemistry
  • Western blot

forma física

Solution, stablilized in 50 mM Triethanolamine buffer, 3 M NaCl, 1 mM MgCl2, 0.1 mM ZnCl2, 10 mg/ml bovine serum albumin, pH 7.6.

Nota de preparo

Working solution: 50 - 1,000 mU/ml (i.e., stock solution can be diluted). Dilute the conjugate stock solution in 100 mM Tris-HCl, 150 mM NaCl, pH 7.5.

Working concentration: Working concentration of conjugate will depend on the application and substrate. Indicated concentrations should be taken as a guideline.

ELISA: 50 - 200 mU/ml (1:5000 - 1:20,000 dilution)
Immunohisto/cytochemistry: 250 - 1,000 mU/ml (1:1000 - 1:4000 dilution)
Western blot: 200 - 500 mU/ml (1:2000 - 1:5000 dilution)

Stability: The concentrated stock solution is stable when stored at 2 to 8°C until the expiration date printed on the label. Do not freeze!

Atherosclerosis is studied in models with dysfunctional lipid homeostasis-predominantly the ApoE-/- mouse. The role of antigen-presenting cells (APCs) for lipid homeostasis is not clear. Using a LacZ reporter mouse, we showed that CD11c+ cells were enriched in aortae of ApoE-/-

Bone morphogenetic proteins play a pivotal role in the epimorphic regeneration in vertebrates. Blastema formation is central to the epimorphic regeneration and crucially determines its fate. Despite an elaborate understanding of importance of Bone morphogenetic protein signaling in regeneration, its
