[Abstract]  

The mammalian neocortex, the outer layer of the cerebrum and most recently evolved brain region, is characterized by its unique areal and laminar organization. Distinct cortical layers and areas can be identified by the protein expression of graded transcription factors and molecular determinants that define the identity of different projection neurons. Thus, specific detection and visualization of protein expression is crucial for assessing the identity of neocortical neurons and, more broadly, for understanding early and late developmental mechanisms and function of this complex system. Several immunostaining/immunofluorescence methods exist to detect protein expression. Published protocols vary with regard to subtle details, which may impact the final outcome of the immunofluorescence.

[Abstract]  Gaboxadol (4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol, THIP), a GABAA receptor δ-subunit specific agonist, when present at low (μM) concentrations, preferentially binds and activates extrasynaptic (non-γ2, δ-subunit-containing) GABAARs (Storustovu and Ebert, 2006; Richardson et al., 2011, 2013).

In this prototype saturation binding experiment, a series of concentrations of [3H]gaboxadol (5, 10, 25, 50, 75, 100, 250 and 400 nM) will be used. GABA at 200 μM will be added into binding mixtures as a cold displacer for [3H]gaboxadol. Slide mailers are used and each requires 7 ml binding mixture. Pre-, post-washing and binding buffer is 50 mM Tris-Citrate (pH 7.1). The detailed procedure is outlined below.
[摘要]  加巴沙朵(4,5,6,7-四氢异恶唑并[5,4-c]吡啶-3-醇,THIP),当存在于低(μM)浓度时,GABA A受体δ-亚单位特异性激动剂优先结合并激活突触后 (非γ2,δ-亚单元)GABAARs(Storustovu和Ebert,2006; Richardson等,2011,2013)。
在这种原型饱和结合实验中,将使用一系列浓度的[3 H]加波沙朵(5,10,25,50,75,100,250和400nM)。 作为[3H]加波沙朵的冷置换剂,将200μM的GABA加入到结合混合物中。 使用幻灯片邮寄员,每个需要7毫克的绑定混合物。 洗脱后和结合缓冲液为50mM Tris-Citrate(pH7.1)。 具体步骤如下。
