熒光手電筒用于觀察茜素紅染色的海馬骨架

用于骨架的染料是茜素紅 S。它可以在白光下觀察，但在適當(dāng)波長(zhǎng)的激發(fā)下它會(huì)發(fā)出美麗的紅色。該圖像是在配備體視顯微鏡熒光適配器的體視顯微鏡上拍攝的，使用綠色 (GR) 激發(fā)光源和匹配的紅色屏障濾光片。

Fluorescence of Cleared and Stained Specimens

We received this beautifully detailed fluorescence image of a seahorse skeleton from Kevin Conway at Texas A&M University. The specimen, a dwarf seahorse (Hippocampus zosterae), was prepared using a technique called ‘clearing and staining’, a method that produces an intact specimen with cartilage stained blue and bones stained red. It is a great way visualize the entire structure of an organism.

The stain used for the skeleton is Alizarin Red S. It can be viewed under white light, but under appropriate excitation it glows a beautiful red. The image was made on a stereo microscope outfitted with the Stereo Microscope Fluorescence Adapter, using the Green (GR) excitation source and matching red barrier filter.

LUYOR-3415RG便攜式熒光激發(fā)光源

一直以來(lái)，脊椎動(dòng)物研究人員都靠所謂的清理和染色的方法（剝離標(biāo)本的軟組織，用紅色染料染色），拍攝詳細(xì)的圖片，進(jìn)行解剖檢查，分析物種之間的關(guān)系。但由于失去了韌帶和肌肉組織，骨骼松弛，很難支撐，科學(xué)家無(wú)法從特定角度進(jìn)行拍攝。脊椎動(dòng)物研究人員利用這些圖像來(lái)探索動(dòng)物的進(jìn)化過(guò)程，并辨別它們與其他物種的共同特征。

如果沒(méi)有組織，像白眼蟒這樣的動(dòng)物，很多骨骼會(huì)柔弱無(wú)骨，無(wú)法定型。但明膠能把它們固定住，拍完照片后再清洗掉。

在LUYOR-3280或LUYOR-3415熒光手電筒照射下，甘油明膠基質(zhì)支撐的紅色染料染過(guò)的海馬骨骼發(fā)著光。這種攝影技術(shù)可以幫助科學(xué)家用一種新方法檢查骨骼。
