Schwann Cell-Sensory Neurons-PNS Markers

Data-Publications
These markers a important tools for the study of Neuro-muscular diseases like Amyotrophic Lateral Sclerosis (ALS) and Multiple Sclerosis (MS).

For Neuromuscular Disease Researchers, we have some of the best Schwann Cell and Sensory/Peripheral Neuron Markers in the business.
Images: Rat mixed neuron/glial cultures stained with Peripherin (green channel) and Neurofilament alpha-internexin/NF66 (green channel). These cultures contain mostly neurons which are rich in alpha-internexin, and a subgroup which have a large amount of peripherin also, such as the prominent cell in the middle of the micrograph. Since this cell expresses large amounts of peripherin and alpha-internexin, the green and red signals superimpose to produce a golden cell. Blue is a DNA stain. Protocol on data-sheet.

Here're recent publications referencing use of these markers:

Images: Micrographs depicting SSeCKS colocalization with myelination markers (CNPase and Pzero). (A) SSeCKS (red) and CNPase (green) in the lumbar spinal cord dorsal horn. The labeling appears discrete with minimal colocalization. (B) SSeCKS (red) and Pzero (green) in the L4 dorsal root ganglia. A lack of co-localization is observed and Pzero can be seen localized to putative axonal elements (arrow). (C) SSeCKS (red) and Pzero (green) in the sciatic nerve. As in the dorsal root ganglia, a lack of co-localization is observed. Both SSeCKS and Pzero can be seen localized to axonal elements. (D) SSeCKS (red) and Pzero (green) in glabrous skin of the hind-paw, fibers displaying colocalization (yellow) can be observed (arrow). Irmen et al.

I will post new data and pubs as they become available.
