文献1:Lux A, Morita S, Abe J, Ito K, 2005.An improved method for clearing and staining free-hand sections and whole-mount samples. Ann Bot (Lond) 96:989–996

A)Clearing solution:Lactic acid was saturated with chloral hydrate.

B)(a) A 0.1 % (w/v) solution of berberine hemisulphate (小檗碱) in lactic acid was dissolved at room temperature. (b) A 0.01 % (w/v) solution of fluorol yellow 088 (荧光黄088, JP4473) in lactic acid was prepared by heating at 70°C for 1h. Due to the low stability of the solution, this was prepared fresh before each use.

C) Clearing and staining procedure

The sections floating in drops of clearing solution on microscope slides were heated over a water bath in covered Petri dishes. Treatment for 1h, using a high temperature (70°C), even with large or dense sections, was usually sufficient. The clearing solution was then absorbed by pipette or tissue paper and the sections were thoroughly washed with distilled water added several times to the sections and absorbed by tissue paper. Sections were post-stained and subsequently washed in the same way. Framing by a liquid blocker (PAP pen) proved useful to prevent the loss of sections from slides.

 

For observation of cell files along the root axis,whole roots were cleared and stained in lactic acid with fluorescence stains (berberine or fluorol yellow) and post-stained with safranin O.This procedure allows observation of epidermal and exodermal cells in thick roots of various species, and in thin roots of arabidopsis it works well for staining and observation of endodermal cells. In thick roots such as those of maize or sorghum, peeling peripheral root tissues exposes the endodermal cells and allows their direct observation. The contrast of cell walls is increased after treatment of peeled samples with berberine in lactic acid.

A)Histochemical observations of suberin and lignin in skin cross sections were achieved by staining with a freshly prepared solution of Fluorol Yellow 088 (0.01% [w/v] in lactic acid) for 30 min at 70°C and phloroglucinol-hydrochloric acid (2% [w/v] in 50% hydrochloric acid) for 30 min at room temperature, respectively. Stained sections were then observed with an Olympus CLSM500 microscope using bright-field and GFP filters. Autofluorescence of cuticle layers in smooth skin sections was observed with a Cy5 filter.

A)For fluorol yellow 088, a final concentration of 0.01% (w/v) was made by dissolving 0.01 g of fluorol yellow 088 in 50 mL of PEG 400 solution and heating at 90°C for 1 h (Brundrett et al., 1991). An equal volume of 90% (v/v) glycerol solution was added to the PEG staining solution. Leaves were stained for 1 h at room temperature, rinsed several times with distilled water, and observed with UV light for a bright yellow fluorescence. Unstained cell walls were also examined for autofluorescence as a test for the phenolic constituents of suberin.

产品描述

硫黄素T(Thioflavin T),又称为碱性黄1(Basic Yellow 1),是一种具细胞膜渗透性的苯并噻唑染料,常用来鉴定样本内淀粉样纤维的存在与否。一旦与淀粉样纤维结合后荧光信号明显增强,结合后引起最大激发波长(385nm→450nm)和最大发射波长(445nm→482nm)的迁移。硫黄素T能用来监测堆积的β折叠,也能用来组织学和蛋白质鉴定。

Representative double fluorescent immunolabelings for Jagged1 (green) and Notch1 (red) counterstained with Thioflavin-T or DAPI (blue) on postmortem brain sections comprising the hippocampal CA fields from healthy age-matched controls and AD patients (A-C). In the healthy controls, Jagged1 is localized to the somata of neurons where also Notch1 is expressed. As expected, Thioflavin-T labeling is negligible (A,A′). AD sections show fibrillary aggregates (B,B′) and (C,C′) core plaques double positive for Notch1 and Thioflavin-T.
