Is there a way to disrupt the protein aggregate?

I used HisTrap to purify a His-MBP tagged protein, and then dialyzed the protein against 20mM Tris-HCl, 150mM NaCl, pH7.4. The protein is pretty soluble and I concentrated to around 10mg/ml, then

Construction aggregate - Wikipedia

Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as

Molecular mechanisms initiating amyloid beta-fibril

The deposition of aggregated amyloid beta-protein (Abeta) in the human brain is a major lesion in Alzheimer' disease (AD). The process of Abeta fibril formation is associated with a cascade of neuropathogenic events that induces brain neurodegeneration leading to the cognitive and behavioral decline characteristic of AD.

Toxicity of substrate-bound amyloid peptides on vascular

Substrate-bound Abeta peptides were found to be toxic to the cells and to increase the rate of cell death. This toxicity was dependent on the length of time the peptide was allowed to 'age', a process by which Abeta is induced to aggregate over several hours to days.

Purification and cloning of amyloid precursor protein beta

Cleavage by beta-secretase at the amino terminus of the Abeta peptide sequence, between residues 671 and 672 of APP, leads to the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated carboxy-terminal fragment. Cleavage of the C-terminal fragment by gamma-secretase(s) leads to the formation of Abeta.

PDF] Roles of proteolysis and lipid rafts in the processing

In the amyloidogenic pathway, the APP (amyloid precursor protein) is proteolytically processed by the beta- and gamma-secretases to release the Abeta (amyloid-beta) peptide that is neurotoxic and aggregates in the brains of patients suffering from Alzheimer's disease. In the non-amyloidogenic pathway, APP is cleaved by alpha-secretase within the Abeta domain, precluding deposition of intact

Abeta to plaques (Lazarov et al. 2002; Stokin et al. 2005). The sites of APP processing and Abeta release have yet remained unclear. Some studies speculate that the axon is the site of Abeta production (Muresan and Muresan, 2006). According to this, amyloid deposition would increase if poor axonal transport delays the progress of APP and its

ABAD directly links Abeta to mitochondrial toxicity in

Mitochondrial dysfunction is a hallmark of beta-amyloid (Abeta)-induced neuronal toxicity in Alzheimer's disease (AD). Here, we demonstrate that Abeta-binding alcohol dehydrogenase (ABAD) is a direct molecular link from Abeta to mitochondrial toxicity. Abeta interacts with ABAD in the mitochondria of AD patients and transgenic mice.
