- 09:53Conclusion
We describe a technique for the preparation of clarified human cortical homogenates, protein separation by SDS-PAGE, antigen retrieval and immunoblotting with an antibody to the Aβ peptide. Using this protocol, we consistently detect monomeric and multimeric Aβ in cortical tissue from humans with Alzheimer's pathology.
