Description
Q-PAGE 4-12 % Tris-Bis Midi gels are ready-to-use polyacrylamide gradient gels for vertical electrophoresis (PAGE). Each Midi cassette measures 10 x 10 cm and carries a 4-12 % polyacrylamide gradient with 12 wells for convenient sample loading. The gels are supplied ready-to-use, so casting and polymerisation steps are eliminated and runs can start promptly. Physical data include a density of approximately 1 g/cm³ and a boiling point near 100 °C. A pack contains 2 pc(s) and is intended for laboratories that routinely separate proteins across a mid-range molecular-weight window. The Tris-Bis buffer chemistry supports common SDS-PAGE and related analytical workflows within the vertical electrophoresis category. These precast gels from manufacturer SMOBIO fit standard Midi tank formats and help standardise gel-to-gel performance. Ideal for preparation and running of PAGE gels in research, quality control and teaching laboratories that value consistent gradient resolution and reduced hands-on gel preparation time.

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.
Which category should I open next?
