HIGHLIGHT: NeuN antibodies: the more they bind, the more they brighten


Biosensis' NeuN antibodies are ideal for defining neurons in intact brain sections, cultures, and organoids. After two decades of discovery, NeuN antibodies are still a key tool for neuroimaging, being cited in more than 6000 publications. Our NeuN antibodies are useful for ICC, IHC, and WB applications and show reactivity in human, mouse, and numerous other species. Biosensis offers the choice of two distinct NeuN antibodies against NeuN/Fox3... read more

Biosensis α-synuclein Rapid ELISA Kit
Alpha synuclein elisa and a


Alpha synuclein is an abundant 140 amino acid neuronal protein associated with a number of neurodegenerative diseases. Aggregated proteinaceous inclusions called Lewy bodies which are found in Parkinson's disease and cortical Lewy body dementia (LBD) have been shown to be predominantly alpha-synuclein.


Alpha-synuclein has also been detected in an increasing number of other neurodegenerative diseases, collectively known as synucleopathies. Alpha-synuclein is therefore a key target in neurodegenerative disease research.


The Biosensis Alpha-Synuclein Rapid ELISA Kit (BEK-2216-1P/2P) lets you quantifiy human alpha-synuclein in plasma, serum and CSF, in under 4 hours with a high level of accuracy... read more about our Biosensis alpha-synuclein ELISA and antibodies.


Fluoro-Jade C Staining Kit for identifying degenerating neurons


Fluoro-Jade C stains all degenerating neurons regardless of the cause of the damage or the mechanism of cell death. Due to its low background and high resolution it provides high contrast staining, making it ideal for localising degenerating nerve cell bodies as well as distal dendrites, axons and terminals. Fluoro-Jade C is resistant to fading making it compatible with most histological processing and staining protocols.

Confidently measure mature BDNF


Brain-derived neurotrophic factor (BDNF) plays essential roles in the central nervous system regulating and supporting the growth, survival and differentiation of neurons. Brain insults or stress can cause variations in BDNF levels, which may contribute to depressive or neurological disorders such as epilepsy and Alzheimer’s disease.


To help researchers quantify BDNF, Biosensis have developed a robust ELISA for mature BDNF with high specificity that can be performed in less than 3 hours with high accuracy, sensitivity and reproducibility... read more and watch the video here.

Why choose a Biosensis sheep α-synuclein antibody?


Our Biosensis sheep anti alpha-synuclein antibodies offer important advantages over anti αlpha-synuclein antibodies raised in mouse and rabbit:


• Validated for multiple applications

• Perfect choice for rodent studies: avoiding cross-reactivity issues with mouse abs

• Optimal partner for mouse and rabbit antibodies in multi-labelling experiments

• Large batch sizes so no need to regularly re-validate as with rabbit antibodies

• Anti-goat secondary abs already in your freezer can be used with a sheep primary

Neurofilaments are a major constituent of the neuronal cytoskeleton and are composed principally of the neurofilament triplet proteins NF-L (light), NF-M (medium) and NF-H (heavy), but may also include peripherin, alpha-internexin, nestin and vimentin


Neurofilaments have a role in a variety of neurodegenerative diseases including multiple sclerosis and amyotrophic lateral sclerosis. They are also incorporated in the structure of intracellular Lewy bodies, in Parkinson’s Disease.

Nerve Growth Factor Receptor (p75NTR)


The nerve growth factor (NGF) receptor, also known as p75 neurotrophin receptor (p75NTR), is a low affinity NGF receptor. The other members of the neurotrophin family, including brain-derived neurotrophic factor (BDNF), neurotrophin (NT)-3 and NT-4/5 bind to p75NTR with equal affinity. This receptor also binds pro-neurotrophins. p75NTR mediates signalling of neurotrophins for neuronal survival, apoptosis, neurite outgrowth and synaptic plasticity. Altered neurotrophin levels and p75NTR expression are implicated in degeneration of spinal motor neurons in human and mouse models of amyotrophic lateral sclerosis (ALS).


Our p75NTR antibody (clone 8J2) to the extracellular domain of p75NTR is ideal for:


- In vivo targeting: retrograde tracing and receptor trafficking

- Flow cytometry, immunopanning, western blot, immunohistochemistry and more.

- Most mammalian species, including human, mouse and rat

- Replacing clone MLR2 (A comparative study can be viewed here).
