IVD Antibody & Immunoassay Development Services for Amyloid-β (Aβ)

Creative Biolabs is a leading service provider that focuses on polyclonal, monoclonal, and recombinant antibody development for research, diagnosis, and potential therapeutics. Based on our extensive experience and state-of-the-art technologies, Creative Biolabs now offers a series of biomarker-specific IVD (in vitro diagnostic) antibody & immunoassay development services to clients globally. Especially, we introduce our IVD antibody & immunoassay development services for the amyloid-β (Aβ) marker.

Introduction to Alzheimer’s Disease

Alzheimer’s disease (AD) is the most common age-related neurodegenerative disease characterized by an insidious onset and a progressive deterioration in cognition, functional ability, and behavior. The pathologic hallmarks of AD include neuritic plaques composed of aggregated amyloid-β peptides (Aβ) surrounded by dystrophic neurites and neurofibrillary tangles composed of hyperphosphorylated tau proteins, accompanied by neuronal and synaptic degeneration. Aβ is generated from amyloid precursor protein (APP) by two subsequent enzymatic steps, through which several Aβ isomers of various chain length can be formed (e.g., Aβ1-38, Aβ1-40, Aβ1-42). These fragments aggregate into Aβ oligomers, ultimately leading to Ab plaques formation.

Aβ as A Diagnostic Marker of AD

Presently, the diagnosis of AD is made largely based on clinical symptoms. Since the pathological processes of AD start decades before the first symptoms, biomarkers may provide the possibility of early disease detection and improve therapeutic outcomes. Currently, the use of Aβ and tau protein markers is recommended in recent research diagnostic guidelines. Aβ positron emission tomography (PET) scan and measurement of cerebrospinal fluid (CSF) biomarkers are validated to aid in the diagnosis of AD. However, these two techniques are either expensive or invasive. Therefore, scientists have focused on the development of immunoassays that detect Aβ in other body fluids such as the plasma and nasal secretions to provide more noninvasive and cheaper techniques. Nevertheless, the concentration of Aβ is lower in the circulation than in the CSF because of the presence of the blood-brain barrier (BBB). The limit of detection of traditional immunoassays, such as ELISA, makes them not sensitive enough for detecting the difference of Aβ between biological samples. As a result, ultra-sensitive technologies are emerging with the potential to provide superior sensitivity and specificity for measuring Aβ in blood samples, including the immunomagnetic reduction (IMR) and the single-molecule array (SIMOA) technique.
