Neurobiology ELISA Kits and Multiplex Immunoassays |
Thermo Fisher Scientific offers a wide selection of sensitive and accurate immunoassays for neurobiology and neuroscience research. These assays include ELISA kits and multiplex immunoassays (for the Luminex technology platform) that allow quantification of biomarkers in cerebrospinal fluid (CSF), plasma, and serum for neuroinflammation, neurodegeneration, traumatic brain injury, and variety of conditions and diseases of the central nervous system (CNS).
Quantification of protein biomarkers is critical for neurobiology and neuroscience research and antibody-based techniques, such as enzyme-linked immunosorbent assays (ELISA) and multiplex immunoassays, offer powerful tools to achieve sensitive quantification. These proteins include neurodegenerative disease biomarkers, traumatic brain injury biomarkers, including those released due to astroglial, axonal, and neuronal cell body injury, neurotrophic factors (NTFs) that play a key role in the development of neurons, their plasticity, protection, repair, and key cytokines and chemokines that are involved in central nervous system (CNS) tissue homeostasis and neuroinflammation (Figure 1).
A variety of conditions or diseases of the CNS including brain trauma, stroke, multiple sclerosis, Parkinson’s disease, or Alzheimer’s disease can trigger neuroinflammation and dysfunction of blood-brain barrier (BBB). Acting in concert with aging, epigenetics, the environment, and other risk factors can strongly influence the onset and progression of these diseases. For example, traumatic brain injury has been established as a risk factor for the development of neurodegenerative diseases and dementia at later stages of life. In response to insults that perturb homeostasis in the CNS, a rapid and early activation of the glial cells form the acute inflammatory response. This leads to the repair of the damaged area but if the challenge is not cleared and persists, the activation of the response is exaggerated, becomes chronic, and can result in tissue degeneration and even the drastic loss of BBB integrity.
Figure 1. Major neuronal and non-neuronal cell types of the CNS and candidate biomarkers for neuroinflammation, brain injury and neurodegeneration. This schematic depicts possible origins of biomarkers for neuroinflammation, traumatic brain injury, and neurodegeneration. Abbreviations: GFAP (glial fibrillary acidic protein); S100B (S100 calcium-binding protein B); NCAM-1 (neural cell adhesion molecule -1); NF-H (neurofilament heavy polypeptide); UCHL1 (ubiquitin carboxyl-terminal hydrolase isoenzyme L1); TREM-2 (triggering receptor expressed on myeloid cells 2); CHI3L1/YKL-40 (chitinase-3-like protein 1/protein with first three N-terminal amino acids, tyrosine (Y), lysine (K), and leucine (L) with apparent molecular weight of 40); sRAGE (soluble receptor for advanced glycation end products); NGF-beta (nerve growth factor-beta); BDNF (brain-derived neurotrophic factor); GDNF (glial cell-derived neurotrophic factor); CTNF (ciliary neurotrophic factor); BACE1 (beta-secretase 1); KLK6 (kallikrein related peptidase 6); TDP-43 (TAR DNA-binding protein - 43).
ELISA enables specific, quantitative measurements of protein from a variety of biological sources including serum, plasma, and cerebrospinal fluid (CSF) from a variety of species. We offer ELISA kits for the study of critical proteins such as Aβ40/Aβ42, phosphorylated Tau, and alpha-synuclein implicated in neurodegenerative disorders.
Invitrogen ELISA kits for popular targets such as BDNF, GDNF, Amyloid beta etc. are listed in Table 1.

Figure 2. Performance data for Human Tau (Total) ELISA. ELISA was performed using standard human Tau (total) ranging from 0–2,000 pg/mL and Tau (Total) Human ELISA Kit. Left panel: Typical 7-point standard curve. The dynamic range is 31–2,000 pg/mL, with an analytical sensitivity of <12 pg/mL. Right panel: recombinant human (Hu) tau protein standard provided in the kit was compared to natural human tau and serially diluted in Standard Diluent Buffer. The optical density of each dilution was plotted against the standard curve. Parallelism between the natural and recombinant protein indicates that the standard accurately reflects natural Hu tau content in the samples.
ProQuantum Immunoassay Kits for neurobiology and neuroscience research are designed to provide quantitative measurements of proteins in small sample volumes. Utilizing proximity-based amplification technology, the assay combines the analyte specificity of high-affinity antibody-antigen binding with the signal detection and amplification capabilities of real-time PCR to achieve a simple yet powerful next-generation protein quantitation platform. A user-friendly no-wash workflow combined with intuitive software for analytics enables sample-to-answer in just two hours. We continue to launch assays for new targets so check back often to see what is available.
Invitrogen ProQuantum immunoassay kits for popular targets such as Tau, Tau pT181 and Troponin I are listed in Table 2. Standard curve of Tau using Human Tau Total ProQuantum Immunoassay Kit is shown in Figure 3.

Invitrogen ProcartaPlex multiplex immunoassay panels provide a powerful biomarker detection tool to help distinguish diseased from non-diseased states and/or even differentiate between neurodegenerative diseases. These Luminex xMAP-based assays allow for the simultaneous measurement and tracking of multiple factors/biomarkers over time and open the avenue of a deeper and more thorough understanding of the progression of neuroinflammation and neurodegenerative diseases. Various biomarker levels were tested in cerebrospinal fluid samples of human adult and pediatric patients using the ProcartaPlex Human Neuroscience Panel, 18plex (Figure 4).

QuantiGene RNA gene expression assays provide a fast and high-throughput solution for multiplexed gene expression quantitation, with simultaneous measurement of up to 80 genes of interest in a single well of a 96- or 384-well plate. The QuantiGene Plex assay is based on hybridization and incorporates branched DNA (bDNA) technology, which uses signal amplification rather than target amplification for direct measurement of RNA transcripts. The assay is run on the Luminex platform, has a simple workflow, and does not require RNA purification. These features allow the user to merge the QuantiGene workflow for gene expression profiling with the ProcartaPlex workflow for protein quantitation (Figure 5) using the same sample.
QuantiGene has been used to study gene expression in many different areas of neurobiology due to its high-throughput and custom nature, and its flexibility to measure any target with a relevant RNA sequence. Alterman et al. applied QuantiGene Plex to establish a high-throughput assay for mRNA silencing in primary cortical neurons in vitro with oligonucleotide therapeutics [1]. In addition, this group also published a divalent siRNA chemical scaffold for potent and sustained modulation of gene expression throughout the central nervous system [2]. Furthermore, QuantiGene Plex was used to evaluate the pharmacokinetics, pharmacodynamics, and tissue distribution of the drug omaveloxolone in monkeys to compare these findings to initial results in Friedreich’s ataxia patients [3]. Bates’ research group studied extensive expression analysis of Htt transcripts in brain regions from the zQ175 Huntington's Disease mouse model using the QuantiGene Plex assay [4] and was subsequently able to show that the heat shock response is impaired in Huntington's Disease mouse models and not caused by HSF1 reduction, as measured by QuantiGene Plex [5]. Multiplex gene expression analysis was key to measure tumor mRNA expression profiles for 92 genes related to angiogenesis and vascularity in glioblastoma samples to assess the vascularity in glioblastoma and its implications on patient outcomes [6].
