SDS-PAGE 分离胶浓度最佳分离范围参考:
6%胶:50-150kD
8%胶:30-90kD
10%胶:20-80kD
12%胶:12-60kD
15%胶:10-40kD
注意事项
1. 过硫酸铵配制成 10%溶液后应当-20℃保存,应尽量减少室温存放时间以防失效。
2. TEMED 有轻微刺激性气味,使用时注意防护。
3. 升温可以加快凝胶的聚合速度。
4. 配胶用丙烯酰胺有神经毒性,可通过皮肤吸收,其作用具有积累性,配制时应戴手套。聚丙烯酰胺(聚合后)无毒,但也应谨慎操作,因为有可能含有少量的未聚合成分。
5. 本产品仅供科研使用,勿作其他用途。
6. 为了您的安全和健康,请穿实验服并佩戴一次性手套操作。
Tris-HCl/SDS Separating Gel Buffer (1.5 mol/L, pH 8.8) is used for preparing separating gel in SDS-PAGE electrophoresis and filtered through a 0.22 μm sterile membrane. Components: 0.4% SDS, 1.5 M Tris, pH 8.8. It is applied to cast the lower separating gel of SDS-PAGE, and no additional 10% SDS is required during gel preparation. This product can be used directly for separating gel preparation. After formulation according to SDS-PAGE separating gel systems of different concentrations (Table 1), the final concentration is 1× working solution.
Instructions for Use
Prepare SDS-PAGE separating gels of various concentrations referring to the formulations in Table 1, or adjust based on personal experience and specific experimental requirements.
Table 1 Formulation of SDS-PAGE Separating Gels with Different Concentrations |
Reference Optimal Separation Range for SDS-PAGE Separating Gels
6% gel: 50–150 kDa
8% gel: 30–90 kDa
10% gel: 20–80 kDa
12% gel: 12–60 kDa
15% gel: 10–40 kDa
Precautions
1.Aliquoted 10% ammonium persulfate (APS) solution should be stored at −20 ℃ and minimize storage at room temperature to avoid inactivation.
2.TEMED has a slight pungent odor; wear proper protection during handling.
3.Elevated temperature accelerates gel polymerization.
4.Acrylamide used for gel casting is neurotoxic, absorbable through the skin with cumulative effects. Wear gloves while preparing gels. Polymerized polyacrylamide is non-toxic, but handle cautiously as trace unpolymerized monomers may remain.
5.For research use only; not for other applications.
6.For your safety and health, wear a lab coat and disposable gloves during operation.
