Application
α-Bungarotoxin-tetramethylrhodamine from Bungarus multicinctus was used at a dilution of 1:220 to identify the distribution of nicotinic acetylcholine receptors at neuromuscular junctions of longitudinal sections of rat gastrocnemius muscle.
α-Bungarotoxin-tetramethylrhodamine from Bungarus multicinctus (Formosan Banded Krait) has been used in immunofluorescence staining (1:200) for identification of neuromuscular junction in experimental models. It has also been used to block muscle contraction in myotome cells.
Biochem/physiol Actions
α-Bungarotoxin is a high-affinity antagonist for nicotinic acetylcholine receptors (AChRs) from muscle but not the neurons. Labeling α-Bungarotoxin with tetramethylrhodamine enables the detection of bungarotoxin-binding receptors at neuromuscular junctions.
Useful for detecting the distribution of nicotinic acetylcholine receptors at neuromuscular junctions.

Peripheral nerve regeneration across long nerve gaps is clinically challenging. Autografts, the standard of therapy, are limited by availability and other complications. Here, using rigorous anatomical and functional measures, we report that aligned polymer fiber-based constructs present topographical cues that

The muscle quality of the rotator cuff (RC), measured by atrophy and fatty infiltration (FI), is a key determinant of outcomes in RC injury and repair. The ability to regenerate muscle after repair has been shown to be limited. To

Spinal and bulbar muscular atrophy (SBMA), also known as Kennedy's Disease, is a late-onset X-linked progressive neuromuscular disease, which predominantly affects males. The pathological hallmarks of the disease are selective loss of spinal and bulbar motor neurons, accompanied by weakness

Neuronal nicotinic alpha7 subunits assemble into cell-surface complexes that neither function nor bind alpha-bungarotoxin when expressed in tsA201 cells. Functional alpha-bungarotoxin receptors are expressed if the membrane-spanning and cytoplasmic domains of the alpha7 subunit are replaced by the homologous regions

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative condition that primarily affects the motor system and shares many features with frontotemporal dementia (FTD). Evidence suggests that ALS is a 'dying-back' disease, with peripheral denervation and axonal degeneration occurring before loss
