192-IgG is the antibody to the p75 neurotrophin receptor (p75NTR). The p75NTR, also known as the low affinity nerve growth factor receptor, binds nerve growth factor, brain-derived neurotrophic factor, neurotrophin-3 and neurotrophin-4 with varying specificities. The p75NTR plays an important role in neurotrophic factor signaling and has been shown to modulate the susceptibility of selective cellular populations to programmed cell death.
This fluorescent conjugate recognizes p75 receptor-positive cells in rat. It was prepared using mouse monoclonal antibody 192-IgG conjugated to Cy3. This product is routinely tested by flow cytometry.
Applications include flow cytometry, immunofluorescence, and immunocytochemistry. This product can also be used as a transport agent.

Summary: Accumulation of β-amyloid in the brain is considered one of the main causes of Alzheimer's disease. The increase in β-amyloid is accompanied by a reduction in levels of the high affinity nerve growth factor receptor (trkA) and cognitive impairment. The authors looked at levels of the low affinity nerve growth factor receptor (p75) that do not decline. Using a 0.8-μg injection of 192-Cy3 (Cat. #FL-01) into the medial prefrontal cortex of rats the authors assessed the transport of p75 and β-amyloid by microscopy. The results indicate that the primary destinations of both p75 and β-amyloid were the late endosome and lysosome.

Summary: The voltage modulation functions of the basal forebrain have commonly been associated with cholinergic cells. More recent work has suggested that noncholinergic cells have an influence on this type of neuronal activity. The authors labeled cholinergic neurons by injecting 0.8-1.6 μg of Cy3-192-IgG (Cat. #FL-01) into the lateral ventricles of rats. Patch-clamp recordings were taken from brain slices of these animals under various blockade conditions. The results demonstrate that neuropeptide Y receptors as well as ions such as Ca2+ and K+ are important for regenerative firing in basal forebrain cholinergic neurons.
