Introduction:

Protein Sample Loading Buffer for Tris-Acetate is a modified protein loading buffer with bromophenol blue as dye and offered at 4× concentration. It can be used to prepare protein samples for denaturing gel electrophoresis using Tris-Acetate PAGE gels. This product contains SDS and DTT.

Storage: Store at -20°C for one year. It is recommended to freeze and store in aliquots to avoid repeated freezing and thawing.

Protocol (for reference only):

1. Mix Protein Sample Loading Buffer for Tris-Acetate (4×) with your protein sample with 1:3 ratio.
2. Heat the sample mixture at 100°C for 3-5 minutes to denature proteins completely.
3. Directly load the sample mixture into the wells of the PAGE gel after it has cooled to room temperature.
4. The electrophoresis can be stopped when bromophenol blue reaches near the bottom of the PAGE gel.

Notes:

1. This product is offered in 4× format and it should be diluted into 1× working solution according to the experimental requirements.
2. For research use only. Not for use in diagnostic procedures.
3. For your safety and health, please wear personal protective equipment and clothing when operating.
