In the realm of biochemical research, the study of proteins and their derivatives remains a cornerstone for understanding cellular mechanisms. Among these, the alpha beta 1-40 peptide—frequently referred to in literature as beta amyloid peptid Amyloid-Beta 1-40 Wild type (1.0 mg) Human, Recombinant e 1-40 or simply Aβ(1-40)—serves as a primary focus for investigators examining protein aggregation and structural biology.
Defining the Molecule: What is Alpha Beta 1-40 Peptide?
At its core, this molecule is a 40-amino-aci Amyloid-Beta 1-40 Wild type (1.0 mg) Human, Recombinant d peptide derived from the larger amyloid pr by S Lehmann·2020·Cited by 67—A decrease in cerebrospinal fluid (CSF) level Aβ1–42 is evident in AD, and the CSF ratio Aβ42/Aβ40 has recently been identified as one of the most reliable Read more ecursor protein (APP). It is a synthetic peptide co Beta amyloid peptide 1-40 mposed of 40 amino acids that mirrors the specific residues found in biological systems. Researchers often utilize recombinant human Amyloid-Beta 1-40 to ensure high purity and consistency across experimental trials.
From a structural perspective, the Aβ peptide (1-40) is characterized by its specific sequence: Asp-Ala-Glu-Phe-Arg-His-Asp-Ser-Gly-Tyr-Glu-Val-His-His-Gln. Because it is a 40-43 amino acid peptide, it is often studied alongside its counterpart, Aβ(1-42). Together, they represent the two major C-terminal variants of the Aβ family. While Aβ(1-42) is often noted for its aggregation properties, Aβ(1-40) remains one of the two most abundant species of amyloid-beta peptides found in extracellular environments.
Research Applications and Analytical Methods
When sourcing these materials for laboratory use, quality control is paramount. High-grade Beta amyloid samples, such as those prepared with HFIP (hexafluoroisopropanol) to maintain a monomeric state, are preferred to minimize pre-existing aggregation. This ensures that the 1-40 sequence behaves predictably during assays.
The substance is a neurotrophic factor that is involv Beta-Amyloid (1-40) Peptide ed in the pathogenic mechanism of Alzheimer's disease models, which makes it a critical tool in neurobiology laboratories. Furthermore, because it is a small peptide present in normal cells, maintaining accurate baseline measurements is essential. Scientists frequently utilize β-Amyloid (1-40) TFA (trifluoroacetate salt) for its stability.
Many researchers rely on sophisticated diagnostic tools, as the material is intended for use as an adjunct to diagnostic evaluations of Alzheimer's disease. To facilitate this, the amyloid-beta 1-40 peptide is often utilized in high-throughput settings, as it is ideal for use with immunoassay technologies and ELISA platforms.
Key Characteristics for Experimental Design
When conducting studies, it is important to distinguish between various forms:
* Synthetic Production: Most laboratory-grade versions are produced synthetically to ensure a precise sequence.
* Structural Insight: As a 40-residue peptide, its folding patterns—specifically the α-helix conformation—are subject to intense scrutiny in structural biology.
* Comparative Studies: As one of the two main forms found in plaques associated with Alzheimer's disease, it provides a critical benchma beta-Amyloid Peptide (1-40) (human) (AB120479) rk for comparing metabolic pathways in different tissue models.
* Versatility: Whether one is seeking Beta Amyloid 1 40 Peptide for metabolic studies or structural analysis, the use of standardized, verified monomeric forms is the industry standard.
