GPX1 是机体核心抗氧化蛋白,依靠谷胱甘肽清除活性氧,减轻氧化损伤,广泛表达于各类体细胞。重组 GPX1 可用于抗氧化机制、氧化应激相关实验研究。蛋白表达失衡会造成氧化稳态失衡,是抗氧化机制、细胞应激研究常用靶点。
Q1: 这款GPX1蛋白覆盖Thr50-Ala202区段,缺失N端前49个氨基酸,是否会影响其酶活性或抗体识别的抗原表位?
A: 该蛋白为截短体形式,保留了GPX1核心催化结构域,适用于免疫与检测实验。由于生物活性测试仍在进行中,若需用于酶活功能研究,建议先进行预实验验证;用于抗体制备时,需确认目标抗体识别表位是否位于Thr50-Ala202区间内。
Q2: 该蛋白的储存缓冲液含有0.02% NLS,在进行酶活性测定时是否需要去除?
A: NLS(月桂酰肌氨酸钠)作为增溶剂有助于蛋白稳定溶解,但可能干扰部分酶学或细胞功能实验。建议在进行活性测定前通过透析、脱盐柱更换缓冲液,或联系技术支持咨询无去污剂的处理方案。
Q3:储存要求与保质期?
A:频繁取用置于 2~8℃存放;长期储存放置在 - 20℃~-80℃环境,收货后有效期 12 个月。需使用手动除霜冰箱,避免反复冻融致使蛋白失活。
Q4: 该蛋白的预测分子量为19.47 kDa,若用于抗体制备,能否产生识别天然全长GPX1的抗体?
A: 可以。该蛋白覆盖了GPX1的主要免疫活性区段,能够诱导产生特异性抗体。但由于N端缺失前49个氨基酸,若需确保抗体识别N端表位,建议使用全长蛋白作为免疫原或进行表位映射验证。
