我可以使用NeuroTrace Nissl 染色剂染色胶质或其他类型细胞，该如何改善染色效果，使其对神经元的选择性更强？

我们的NeuroTrace Nissl 染色剂可标记Nissl底物——该底物由与粗面内质网相关的核糖体RNA构成，并大量存在于神经元中。这些染料并非完全特异性靶向神经元，但由于神经元蛋白质的合成水平高而对神经元选择性染色。在某些情况下它们可能会对其他类型细胞（如神经胶质细胞）染色，所以你可能需要降低染色浓度以获得更具选择性的神经元标记效果。对于神经元染色，我们建议的稀释范围是20到300倍。

NeuroTrace Nissl染色剂可染色石蜡切片吗？

我们只在小鼠脑冰冻切片上测试过，但是有文献指出NeuroTrace Nissl 染色剂可染色石蜡切片。

NeuroTrace Nissl 染色剂是什么?

这些染料是保密的，但它们是标记Nissl物质的染色剂。Nissl物质由与粗面内质网相关的核糖体RNA构成，并大量存在于神经元细胞中。

I am labeling brain cryosections with a NeuroTrace Nissl Stain. Is this compatible with antibody labeling?

Yes. We have done this successfully with an anti-GFAP primary and an Alexa Fluor secondary antibody. We would recommend labeling with the primary and secondary antibodies first, then following up with the standard NeuroTrace Nissl Stain protocol.

I can use the NeuroTrace Nissl stains for staining glia or other cell types. What can I do to improve the staining so that it is more selective for neurons?

Our NeuroTrace Nissl stains label the Nissl substance which is composed of ribosomal RNA associated with the rough endoplasmic reticulum and is present in high amounts in neuronal cells. These dyes are not completely specific for neurons, but will selectively stain neurons based on their high level of protein synthesis. In some cases they may show staining of other cell types such as glia, so you may need to decrease the staining concentration to obtain more selective neuronal labeling. We suggest dilutions in the range of 20- to 300-fold for neuronal staining.

Can the NeuroTrace Nissl stains be used on paraffin sections?

We have only tested them on mouse brain cryosections, however, there is at least one citation describing their use on paraffin tissue sections (Michelle L. Schlief, Ann Marie Craig, and Jonathan D. Gitlin. NMDA Receptor Activation Mediates Copper Homeostasis in Hippocampal Neurons. The Journal of Neuroscience, January 5, 2005, 25(1):239 - 246).

What are the NeuroTrace Nissl stains?

The dyes are proprietary, however they are stains that label the Nissl substance, which is composed of ribosomal RNA associated with the rough endoplasmic reticulum and is present in high amounts in neuronal cells.
