Product details:
Human Agrin ELISA Kit ab216945 is a rapid single-wash 90-min Sandwich ELISA to measure Human Agrin in cell culture extracts, cell culture supernatant, CSF, citrate plasma, EDTA plasma, heparin plasma, serum, tissue extracts, urine. This SimpleStep sensitivity is 4.6 pg/mL.
How the assay works
Human Agrin SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Agrin is a heparan sulfate basal lamina glycoprotein that plays a central role in the formation and the maintenance of the neuromuscular junction (NMJ) and directs key events in postsynaptic differentiation. Agrin is a component of the AGRN-LRP4 receptor complex that induces the phosphorylation and activation of MUSK. The activation of MUSK in myotubes induces the formation of NMJ by regulating different processes including the transcription of specific genes and the clustering of AChR in the postsynaptic membrane. Calcium ions are required for maximal AChR clustering. Agrin function in neurons is highly regulated by alternative splicing, glycan binding and proteolytic processing. Agrin modulates calcium ion homeostasis in neurons, specifically by inducing an increase in cytoplasmic calcium ions. Agrin functions differentially in the central nervous system (CNS) by inhibiting the alpha(3)-subtype of Na+/K+-ATPase and evoking depolarization at CNS synapses.

Agrin also known as AGRN is a large heparan sulfate proteoglycan with a molecular mass of approximately 200 kDa. This protein is mainly expressed in the neuromuscular junction and the central nervous system. Agrin has significant roles in synapse formation. It influences the clustering of acetylcholine receptors at the neuromuscular junction which is essential for communication between nerve and muscle cells. This activity is mechanically mediated through interactions with the receptor tyrosine kinase MuSK and LRP4.
Biological function summary
The Agrin protein contributes to the stabilization of synaptic structures. Its ability to induce acetylcholine receptor clustering is fundamental for the proper formation and maintenance of neuromuscular synapses. Agrin is not a lone player; it is a part of a larger signaling complex. This complex includes other proteins like MuSK which acts as a receptor playing an essential role in complex signaling pathways that regulate synaptogenesis and synaptic plasticity.
Pathways
Many molecules associate to facilitate communication and synapse integrity via Agrin's activity. Agrin engages primarily with the MAPK/ERK signaling pathway and the PI3K/AKT pathway. These pathways are central for cell growth and differentiation in the central nervous system. The relationship with MuSK through these pathways highlights Agrin's importance in orchestrating the synapse assembly and stability.
Mutations or alterations in Agrin can lead to conditions such as congenital myasthenic syndromes and potentially impact neurodegenerative disorders like amyotrophic lateral sclerosis. In these cases its interaction with proteins like MuSK is affected leading to impaired neuromuscular transmission. Understanding the anti-Agrin antibody's function might enhance methodologies to treat these neuromuscular disorders.
