Description
Q-PAGE 4-12 % Tris-Bis Midi is a ready-to-use precast gradient polyacrylamide gel for PAGE electrophoresis. The midi cassette measures 10 x 10 cm and contains a 4–12 % polyacrylamide Tris-Bis gradient with 15 wells, combining a broad separation range with a multi-sample well layout. Each pack provides 2 pc(s), so gels can be used directly without preparing gradient gels in the laboratory. Physical characteristics include a density of about 1 g/cm³ and a boiling point near 100 °C. The product is available from manufacturer SMOBIO and is intended for midi tanks that accept 10 x 10 cm cassettes. Fifteen wells support simultaneous loading of multiple samples and references on one gradient gel. Approximate pack weight is 0,181 kg. This 4–12 % Tris-Bis midi gradient format suits vertical electrophoresis workflows where a continuous polyacrylamide range and a ready-to-use cassette are preferred over hand-cast gradient gels, within standard PAGE preparation and precast gel applications.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about Q-PAGE 4-12 % Tris-Bis Midi
What is this article?
Q-PAGE 4-12 % Tris-Bis Midi is the article on this page. Luminix Health distributes SMOBIO for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Produits chimiques.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
