生物活性

β-Amyloid 22-35 (Amyloid β-Protein 22-35), the residues 22-35 fragment ofβ-amyloid protein, has a cytotoxic effect on cultured neurons from the rat hippocampus in serum-free medium. β-Amyloid 22-35 forms aggregates and typical amyloid fibrils resembling those of the β-amyloid protein in neutral buffer solution)[1].

IC50 & Target

Amyloid-β[1]

体外研究
(In Vitro)

β-Amyloid 22-35 shows significant cytotoxicity on the rat hippocampal neurons at 40 μg/mL, but exhibits no cytotoxic effect on the glial cells[1].

Cell Assay
[1]

Hippocampal cells are cultured in DMEM supplemented with 10% (v/v) precolostrum newborn calf serum in poly-D-lysine-coated 24-well culture plates at 37°C under a gas mixture of 95% air/5% CO2. After 6 days of culture, non-neuronal cell division is halted by 24 h exposure to 10-5 cytosine arabinoside. After washing cell layers with DMEM, cells are cultured with 1 mL of DMEM per well in the absence of serum for 5 days before experiment. Cells are treated for 3 days with β-Amyloid (22-35) or its amidated (C-terminus) derivative by addition of 20 μL of stock solution (2 mg/mL of either in betaine buffer, pH 8.5, consisting of 0.7% betaine and 20 mM NH4HCO3) to 1.0 mL medium, unless otherwise specified. Control cells are treated with the betaine buffer alone. Morphological change of cells is checked throughout the course of experiment with a phase-contrast microscope. Dead cells are checked by trypan blue staining. Cell injury is assessed by measuring lactate dehydrogenase (LDH) activity released into medium during 3 days of treatment of neurons with peptides[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
