本品专为快速高效封闭Western Blot转印膜而设计,采用无蛋白配方,避免抗体与封闭剂的非特异结合,最大程度地降低了背景。同时,本封闭剂无内源的磷酸化蛋白及生物素,对磷酸化特异抗体及生物素检测也不会产生干扰。本封闭剂不与蛋白产生非特异性结合,因而只封闭膜而不会屏蔽样品蛋白的抗体识别位点,大大提高了抗体检测灵敏度。实验表明,本封闭剂对许多抗体都有不同程度的信号增强作用。然而这种信号增强作用因抗体而异,对某一特定抗体,并不一定具有确定的信号增强作用。
注意:没有任何一种封闭剂能适合所有抗原和抗体的检测系统。如出现本试剂不适合的抗体,请替换使用其它种类的封闭剂,如BSA或脱脂奶粉等。
产品特点:
1. 快速高效:5~10 min 快速完成封闭;只结合封闭转印膜而不结合蛋白,因此不会屏蔽样品蛋白的抗体识别位点,与传统的脱脂奶粉和BSA封闭相比信噪比更高。
2. 方便快捷:无需稀释,即取即用。
3. 性能可靠:无蛋白配方,与抗体无交叉反应。
4. 应用范围广:无磷酸化蛋白,无生物素,尤其适合磷酸化特异抗体及生物素检测系统。
5. 节省抗体:使用本封闭液后,所需的最适抗体浓度低于常规使用浓度,可大大节省抗体使用量。
使用说明:
1. 完成转膜后,将转印膜放入到杂交孵育盒中,加入10~20 mL 无蛋白快速封闭液 ,置于摇床轻轻摇动,室温封闭约10 min(即配即用)。
注意:使用本品通常封闭5~15 min均可;经多种抗体的测试封闭10 min的效果显著优于常规的BSA封闭1h。对于一些背景非常高的抗体,可以尝试将封闭时间延长为30~60 min。如有特殊需要,也可4℃封闭过夜。
2. 封闭后的膜即可用于一抗孵育等后续实验。
注意事项:
1.本产品也可以用于免疫组化 (IHC) 和免疫荧光 (IF) 实验的封闭操作。
2. 为了您的安全和健康,请穿实验服并戴一次性手套操作。
3. 本产品仅限科研使用。
This product is specially formulated for rapid and efficient blocking of Western Blot transfer membranes. Its protein-free formula prevents non-specific binding between antibodies and blocking agents, minimizing background signals. Additionally, this blocking reagent contains no endogenous phosphorylated proteins or biotin, so it will not interfere with phosphorylated-specific antibody detection or biotin-based detection systems. It does not bind non-specifically to sample proteins, meaning it only blocks the membrane without masking antibody recognition sites on target proteins, significantly improving antibody detection sensitivity. Experiments confirm that this blocking reagent enhances signal intensity for many antibodies to varying degrees. However, this signal enhancement effect is antibody-specific and cannot be guaranteed for any single particular antibody.
Note: No single blocking reagent is compatible with all antigen and antibody detection systems. If this reagent yields unsatisfactory results with a specific antibody, switch to alternative blocking agents such as BSA or non-fat dry milk.
Product Features:
1. Rapid & High-efficiency: Complete blocking within 5–10 minutes. It binds only to the transfer membrane rather than sample proteins, so antibody recognition sites remain intact, delivering a higher signal-to-noise ratio compared with traditional blocking methods using non-fat dry milk or BSA.
2. Easy to Use: Ready-to-use, no dilution required.
3. Reliable Performance: Protein-free formulation with no cross-reactivity with antibodies.
4. Broad Compatibility: Free of phosphorylated proteins and biotin, ideal for phosphorylated-specific antibody assays and biotin detection systems.
5. Antibody Saving: Optimal working antibody concentrations are lower than standard protocols, greatly reducing antibody consumption.
Instructions for Use:
1. After membrane transfer, place the blot in a hybridization incubation box, add 10–20 mL of protein-free rapid blocking solution, and incubate on a gentle shaker at room temperature for approximately 10 minutes (use as prepared).
Note: A blocking duration of 5–15 minutes is generally acceptable. Validation across multiple antibodies shows that 10-minute blocking achieves superior results compared to 1-hour conventional BSA blocking. For antibodies with high background, extend blocking time to 30–60 minutes. Overnight blocking at 4°C is also acceptable if required.
2 .The blocked membrane is ready for primary antibody incubation and subsequent experimental procedures.
Precautions:
1. This product may also be used for blocking in Immunohistochemistry (IHC) and Immunofluorescence (IF) experiments.
2. Wear a lab coat and disposable gloves during handling for personal safety and health protection.
3. For research use only.
