12% SDS-PAGE Resolving Gel BufferMaster Mix

Cat. No.: R743049

Overview

Aladdin's 12% SDS-PAGE Resolving Gel Master Mix contains almost all reagents required for the preparation of 12% SDS-PAGE resolving gels, except for polymerization catalysts such as ammonium persulfate and TEMED.Aladdin's SDS-PAGE Resolving Gel Master Mix series can be used to prepare 5 common concentrations of gels

Precautions：

Ammonium Persulfate or its substitute (, ST005) and TEMED are required but not provided in this product.This product contains Acr-Bis which is potentially neurotoxic. Please take effective measures to avoid direct contact with the human body or inhalation.This product is for R&D only. Not for drug, household, or other uses.For your safety and health, please wear a lab coat and disposable gloves during the operation.

Instructions for Use：

1.According to the size of a target protein, decide an appropriate concentration of SDS-PAGE resolving gel. Please refer to the table below.SDS-PAGE Resolving Gel Concentration Optimal Separation Range6%50-150kD8%30-90kD10 -80kD12%12-60kD15%10-40kD2.Prepare a 10% ammonium persulfate solution with ddH2O or other high-purity water. Solution of ammonium persulfate or its substitute is prone to failure and should be prepared freshly or kept frozen for multiple uses.3.Prepare the resolving gel according to the table below. For example, add 100μl of 10% ammonium persulfate and 4μl of TEMED into 10ml of 12% SDS-PAGE Resolving Gel Master Mix, mix well, and immediately pour into gel cassette. Overlay with the top layer of water-saturated butanol, isopropanol, 0.1% SDS or distilled water. Leave at room temperature (~25℃) until fully solidified (usually within 10-30 minutes). Note: The amount of polymerization catalyst in the table below is recommended for polymerization at 25℃. It can be adjusted appropriately according to the temperature. For example, when the room temperature is lower than 20℃, add more TEMED and 10% ammonium persulfate appropriately to promote gel solidification.ReagentsVolume of each component (ml) required for different volumes of SDS-PAGE resolving gel12% SDS-PAGE Resolving Gel Master Mix5101520305010% ammonium persulfate or its substitute0.050.10.150.20.30.5TEMED 0.0020.0040.0060.0080.0120.024.After complete polymerization of the resolving gel, remove the liquid used for sealing, and then prepare the SDS-PAGE stacking gel with 's SDS-PAGE Stacking Gel Master Mix .5.If the prepared gel is not to be used on the same day, it can be stored at 4℃ for 1-2 days.
