常见问题解答 (FAQ)

如果我将SYPRO Orange或SYPRO Red染色液的终浓度增加至1X以上,会增强染色蛋白质的信号吗?

不会。染料浓度高于1X不会带来更好的检测结果。相反,随着染料浓度的增加,背景荧光会增强,染料会发生自淬灭,从而降低信号。

经SYPRO Ruby、SYPRO Orange或SYPRO Red染色的凝胶能否干燥?

经过SYPRO染料染色的凝胶可放置在玻璃纸之间进行干燥,但有时会轻微降低灵敏度。如果在纸上干燥凝胶,光会散射且灵敏度会降低。不推荐使用其他塑料,因为通常使用的塑料是不可透过紫外光的。

我能否使用SYPRO Orange蛋白质凝胶染料对Invitrogen凝胶进行染色?

可以,您可使用SYPRO Orange蛋白质凝胶染料对Invitrogen凝胶进行染色,但需要更改实验方案。该染料主要是与0.05% SDS电泳缓冲液一起使用,但我们所有的缓冲液均含有0.1% SDS。这会产生较高的背景,因为SDS会与染料紧密结合。以下是获得最佳Invitrogen凝胶染色结果的推荐方案:

洗涤液:7.5% (v/v) 乙酸

染色液:在洗涤液中按1:5000稀释SYPRO Orange
1.凝胶电泳完毕后,在100 ml洗涤液中清洗10分钟。
2.将凝胶置于染色液中,在暗处放置长达24小时。
3.从染色液中取出凝胶,在100 ml洗涤液中短暂清洗。
4.随后,可对凝胶进行拍照。

我能否使用SYPRO Ruby、SYPRO Orange或SYPRO Red蛋白质凝胶染料对蛋白质进行预染,然后将蛋白质在凝胶上进行电泳?

不能。上样溶液含有很多SDS,因此,SYPRO Ruby、SYPRO Orange和SYPRO Red染料会只与游离的SDS结合,而极少与蛋白质结合。在电泳前,可预先使用ATTO-TAG CBQCA(货号A2333)、DDAO琥珀酰亚胺酯(货号C34553)或TAMRA-琥珀酰亚胺酯(货号C2211)染料或TC-FLAsH表达分析检测试剂盒(货号A10067为橙黄色荧光,货号A10068为红色荧光)对蛋白质进行共价标记,不会影响蛋白质在凝胶中的迁移。

电泳期间,可将SYPRO Orange或SYPRO Red蛋白质凝胶染料稀释5000倍并加入到阴极(上层)缓冲液槽中,对蛋白质进行染色而不影响迁移。这样做可能引起的问题是,染料与SDS的相互作用可能导致凝胶产生背景荧光。在电泳后使用7.5%乙酸脱色15–60分钟,可降低这种背景荧光。这种染色方法还会导致蛋白质灵敏度低于标准的后染色方法、在凝胶成像前需要相同的时间以及污染电泳装置。

If I increase the final concentration of my SYPRO Orange or SYPRO Red staining solution above 1X, can I increase the signal of my stained proteins?

No. Dye concentrations higher than 1X do not give better detection. Instead, background fluorescence increases and, as the dye concentration increases, the dye becomes self-quenching and the signal actually decreases.

Abstract
LXXLL-related motifs in Dax-1 have target specificity for the orphan nuclear receptors Ad4BP/SF-1 and LRH-1.
Authors:Suzuki T, Kasahara M, Yoshioka H, Morohashi K, Umesono K
Journal:Mol Cell Biol
PubMed ID:12482977
The orphan receptor Ad4BP/SF-1 (NR5A1) is a constitutive activator, and its activity is repressed by another orphan receptor, Dax-1 (NR0B1). In the present study, we investigated the molecular mechanisms underlying this repression by Dax-1. Yeast two-hybrid and transient-transfection assays confirmed the necessity of three LXXLL-related motifs in Dax-1 for interaction ... More
Translational regulation of prostaglandin endoperoxide H synthase-1 mRNA in megakaryocytic MEG-01 cells. Specific protein binding to a conserved 20-nucleotide CIS element in the 3'-untranslated region.

Prostaglandin endoperoxide H synthase-1 (PGHS-1) is an abundant enzyme in platelets, where it plays a key role in the cascade of prostanoid formation. In platelets, the primary site of PGHS-1 synthesis is in precursor megakaryocytic cells. We have previously shown that in megakaryocytic MEG-01 cells, TPA induces an increase of ... More

'Synaptic vesicle exocytosis requires three SNARE (soluble N-ethylmaleimide-sensitive-factor attachment protein receptor) proteins: syntaxin and SNAP-25 on the plasma membrane (t-SNAREs) and synaptobrevin/VAMP on the synaptic vesicles (v-SNARE).
