Protein Sample Loading Buffer (Denaturing, non-Reducing, 5×) - BioReagent, for PAGE, for western blot, suitable for electrophoresis, 5×

Cat. No.: P1492036
AVAILABLE TO ORDER
GRADE & PURITY BioReagent ? BioReagent grade — tested suitable for life-science and molecular-biology use. Use for cell culture, assays, and biochemical work needing biological compatibility. Suitable for electrophoresis ? Electrophoresis grade — low ionic/UV impurities for clean gel runs. Use in agarose/PAGE electrophoresis where impurities distort bands. for PAGE ? PAGE grade — purity suited to polyacrylamide gel electrophoresis. Use for protein/nucleic-acid PAGE where reagent purity affects resolution. for Western blot ? Western-blot grade — suited to protein transfer and immunodetection. Use in Western workflows where reagent purity keeps background low.

Overview

  This product is an improved, 5× concentrated protein loading buffer containing Bromophenol Blue as a tracking dye. It includes denaturing agents but excludes reducing agents such as DTT or β-mercaptoethanol. It is suitable for routine denaturing non-reducing polyacrylamide gel electrophoresis (SDS-PAGE) of protein samples.
Protocol
1.Add 1 volume of loading buffer to 4 volumes of protein sample (1:4 ratio) and mix thoroughly.
2.Heat the mixture in a boiling water bath for 3–5 minutes.
3.After cooling, centrifuge at high speed for 5 minutes. Use the supernatant for electrophoresis.
3.1 Note: If no insoluble debris is observed after adding the loading buffer, brief centrifugation is sufficient to collect the mixture.
3.2 If condensation forms on the tube lid after heating, gently flick the tube to mix the condensation with the sample before centrifugation to ensure uniform loading concentration.
Precautions
1.Wear a lab coat and disposable gloves for safety.
2.For research use only.
