| Description | β-Amyloid (1-42) (Amyloid β-peptide (1-42), human TFA, a 42-amino acid peptide that has not been treated with HFIP, is a brain-penetrant amyloid protein fragment, which can be used in research on Alzheimer's disease and Down’s syndrome. β-Amyloid (1-42), human TFA remaining as aβ-Amyloid (1-42) (Amyloid β-peptide (1-42), human TFA, a 42-amino acid peptide that has not been treated with HFIP, is a brain-penetrant amyloid protein fragment, which can be used in research on Alzheimer's disease and Down’s syndrome. β-Amyloid (1-42), human TFA remaining as a monomer exhibits antioxidant and neuroprotective effects. β-Amyloid (1-42), human TFA, after being monomericized by HFIP and dissolved in DMSO to form the stock solution, on the one hand, can form soluble oligomers (AβOs) when incubated at 4 °C, which have synaptic toxicity and neurotoxicity; on the other hand, it can be incubated at 37 °C to form insoluble fibrils, with lower neurotoxicity, and participating in the oxidative damage process. Aβ42 oligomers bind to various neuronal surface receptors (such as PrPc, mGluR5, NMDA receptors, etc.), triggering oxidative stress, calcium homeostasis imbalance, and synaptic toxicity via activating downstream signaling pathways, leading to neuronal dysfunction and death[1][2][3][4][5][6][7]...

Exhibiting a unique glycosylation pattern that differentiates it from serum Conalbumin (Ovotransferrin), also known as ovotransferrin, is a monomeric glycoprotein consisting of 686 amino acids, encoded by the avian transferrin gene in the oviduct, and a prominent component of chicken egg white. Exhibiting a unique glycosylation pattern that differentiates it from serum transferrin, Conalbumin is a potent iron binder that plays a crucial role in iron transport to developing embryos. Additionally, it possesses a range of biological activities, including antimicrobial, antifungal, antiviral, anticancer, antioxidative, antihypertensive, and immunoregulatory properties, making it valuable in numerous applications such as infant formula ingredients, food additives, and agents for enhancing animal health...

HEXA-HIS can bind to affinity chromatography media containing transition metal ions like nickel (Ni2+) or cobalt (Co2+), making it useful for protein purification[1][2] | Mastoparan, a tetradecapeptide which is a component of wasp venom, stimulates release of prolactin from cultured rat anterior pituitary cells | Neuropeptide SF human augments paraventricular corticotrophin-releasing hormone (CRH) release and increases adrenocorticotropic hormone (ACTH) and corticosterone levels in the plasma.
