SouthernBiotech封片劑—抗熒光淬滅封片劑

更新時(shí)間:2023-10-12   點(diǎn)擊次數(shù):510次

熒光淬滅又稱熒光熄滅或萃滅,是指導(dǎo)致特定物質(zhì)的熒光強(qiáng)度和壽命減少的所有現(xiàn)象。引起熒光淬滅的物質(zhì)稱為熒光淬滅劑。SouthernBiotech專門開發(fā)的Fluoromount-G系列熒光封片劑是以甘油為基礎(chǔ),加入抗熒光淬滅劑,可明顯降低熒光淬滅現(xiàn)象,提高樣本中熒光信號(hào)的穩(wěn)定性和持久性。

 

Fluoromount-G®(貨號(hào):0100-01)

Fluoromount-G®是一種水溶性封片劑,用來(lái)對(duì)最后一步染色為水溶液體系的玻片樣本進(jìn)行封片,可以明顯降低熒光顯微鏡下玻片樣本分析中的熒光淬滅現(xiàn)象。據(jù)報(bào)道,F(xiàn)luoromount-G®的折射率約為1.4。Fluoromount-G®已有超過20,000多篇文獻(xiàn)引用,與100多種熒光染料和試劑兼容。具體詳情,請(qǐng)聯(lián)系SouthernBiotech代理商欣博盛生物!

DAPI Fluoromount-G®(貨號(hào):0100-20)

DAPI Fluoromount-G®是一種水溶性的、含DAPI的化合物,用來(lái)對(duì)最后一步染色是在水溶液體系中完成的玻片樣本進(jìn)行封片。當(dāng)與DNA結(jié)合時(shí),DAPI會(huì)發(fā)出熒光,通常用作細(xì)胞核/染色體復(fù)染物。由于DAPI Fluoromount-G®是水溶性的,可以通過將玻片浸入PBS溶液中直到蓋玻片松開來(lái)移除蓋玻片。
