一般說明
SYPRO Orange与SYPRO Red相似，但它颜色更亮一些，背景荧光略高。 对于使用激光激发凝胶扫描仪的用户，推荐使用一种基于氩离子激光的SYPRO Orange仪器。 该染料可由紫外线或宽带照明光有效激发。它不适用于印迹或IEF凝胶中蛋白的染色，并在2维凝胶染色中显示出较低的灵敏度。
SYPRO Orange为：
SYPRO Orange为：
- 高灵敏度。 该染色剂可检测每minigel条带中1-2ng的蛋白质，比考马斯亮蓝或银染色更灵敏。
- 快速。 在不到1小时内完成染色。
- 简单。 电泳后，对凝胶进行染色、冲洗并拍照；不需要固定或脱色步骤
- 与标准实验室设备兼容。 染色蛋白可以用标准的300纳米紫外透照仪或激光扫描仪来观察。
- 物美价廉。 SYPRO Orange染色法较银染法便宜，并且所需时间短。
- 不同蛋白间变化小。 染料与蛋白质周围的SDS包被层相互作用，使不同类型的蛋白质之间的染色比考马斯或银染色更一致。
- 对蛋白的选择性。 SYPRO Orange检测的蛋白质小至6.5 kDa，不染色核酸或脂多糖。 它染色糖基化蛋白。
- 较宽的检测线性范围。 染色条带的荧光强度与超过3个数量级的蛋白量呈线性相关(比考马斯染色或银染色范围更广)。
應用
SYPRO Orange蛋白凝胶染色技术已应用于蛋白质的热变性和热转移实验。它也被用于微分扫描荧光法。
注意
SYPRO储液应在室温、4°C或20°C下干燥保存并避光。如果储存得当，这些储液可以稳定使用6个月到1年。使用缓冲液或醋酸溶液稀释后的染色试剂可以储存在非常干净、无去污剂的玻璃瓶或塑料瓶中，在4℃下避光保存至少3个月。
