b-amyloid , human

Amyloid β Peptide (42-1)(human) acetate is the inactive form of Amyloid β Peptide (1-42). Amyloid β Peptide (42-1)(human) acetate is a 42-amino acid peptide which plays a key role in the pathogenesis of Alzheimer disease.

β-Amyloid (1-42), acetate (human) is a peptide consisting of 42 amino acids that is part of β-Amyloid and is commonly used in Alzheimer's disease modeling.

β-Amyloid (42-1), human is the inactive form of Amyloid β Peptide (1-42) which plays a key role in the pathogenesis of Alzheimer disease.

'(Des-Bromo)-Neuropeptide B (1-23) (human)' is an agonist for orphan G-protein-coupled receptors, exhibiting a K i of 1.2 nM for GPR7 (NPBW1) and 341 nM for GPR8 (NPBW2) respectively [1].

Orexin B, human (TFA) is an endogenous agonist at Orexin receptor with Kis of 420 and 36 nM for OX1 and OX2.

β-Amyloid precursor protein (96-110), cyclized (human), a segment of the amyloid precursor protein, serves as a research tool in Alzheimer’s disease studies [1].

β-Amyloid(28-35) human is a neurotoxic β-amyloid peptide fragment that contributes to Alzheimer's disease pathogenesis by interacting with neuronal membranes, modulating its secondary structure and toxicity. It also exhibits anisotropic effects on the acidic phospholipid DPH, thereby increasing the internal fluidity within lipid membrane bilayers [1].

β-Amyloid(17-28) human is a fragment of the β-amyloid peptide (Abeta) associated with Alzheimer's disease (AD), promoting the aggregation of the full-length β-Amyloid40 into toxic aggregates [1]. This lipid-induced amyloid core segment is implicated in AD pathogenesis.

Amyloid-β (25-35) (Aβ (25-35)) is an 11-residue fragment of the Aβ protein that retains the physical and biological characteristics of the full length peptide. It forms fibrils that react to thioflavin T and Congo red and are organized in a cross-β arrangement of β-strands similar to Aβ (1-40) and Aβ (1-42) fibrils. Aggregated Aβ (25-35) decreases the viability of rat adrenal PC12 cells. It also decreases the viability of primary rat cortical neurons at concentrations ranging from 1 nM to 30 μM. In vivo, intracerebral injection of Aβ (25-35) (20 nmol) in rats induces lesions of neuronal and tissue loss. Aggregated Aβ (25-35) administered intracerebroventricularly to rats induces learning and memory impairments in the Y-maze, novel object recognition, and contextual fear conditioning tests.

β-Amyloid (1-42), human is a 42-amino acid peptide which plays a key role in the pathogenesis of Alzheimer disease.

β-Amyloid (1-37) (human) Potentially associated with mental status in Alzheimer's disease.

The amyloid β-protein is a 39- to 43-amino acid polypeptide that is the primary constituent of senile plaques and cerebrovascular deposits in Alzheimer's disease and Down's syndrome. Additionally it acts as an inhibitor of the ubiquitin-dependent protein degradation in vitro.

FibrinopeptideB,human is a 14-amino acid polypeptide released from the amino terminus of the fibrinogen segment.

Biotin-β-Amyloid (1-42), human TFA, also known as Biotin-Amyloid β-Peptide (1-42) (human) TFA, is a biotin-labeled 42-amino acid peptide implicated in the pathogenesis of Alzheimer's disease [1].

[Ala11,D-Leu15]-Orexin B(human) TFA is a potent, selective agonist for the orexin-2 receptor (OX2), demonstrating 400-fold higher selectivity for OX2 (EC 50 =0.13 nM) compared to the orexin-1 receptor (OX1) with an EC 50 of 52 nM.

β-Amyloid (42-1), human TFA, a 42-amino acid peptide, represents the inactive form of Amyloid β Peptide (1-42) and is pivotal in the development of Alzheimer's disease [1].

Orexin B, human is an endogenous agonist at Orexin receptor with Kis of 420 and 36 nM for OX1 and OX2, respectively. Orexin B is a hypothalamatic neuropeptide stimulating food intake in rats.

β-Amyloid (1-43)(human) TFA exhibits greater aggregation tendencies and heightened toxicity compared to its well-established counterpart, Aβ1-42. Additionally, this compound demonstrates associations with both sAPPα and sAPPβ. It has the potential to serve as an additional biomarker for Alzheimer’s disease (AD), complementing existing markers [1].

Highly potent and selective OX2 receptor agonist; displays 400-fold selectivity over OX1 receptors. EC50 values are 0.13 and 52 nM for human OX2 and OX1 receptors respectively.

Orexin B, human (TFA), functions as a native agonist for the Orexin receptor, exhibiting dissociation constants (Kis) of 420 nM for OX1 and 36 nM for OX2, respectively.

Fibrinopeptide B (FPB) is produced during the cleavage of fibrinogen, by thrombin, to fibrin monomer.

β-Amyloid (1-42), (rat/mouse) (TFA) is a peptide fragment consisting of 42 amino acids that can be used to study Alzheimer's disease.
