Cas 1132-61-2 Mops Good Buffer Solutions 3-Morpholine Propane Sulfonic Acid

MOPS (3-morpholine propane sulfonic acid) is a kind of zwitterionic buffer, namely Good's buffer, is a series of N-substituted amino sulfonic acid, has good pH stability, high polarity, and is suitable for many chemical reagents. And enzymes are inert, do not participate in or interfere with the process of biochemical reactions, and have no inhibitory effect on enzymatic chemical reactions, so it can be specially used for the research of organelles and extremely variable, pH-sensitive proteins and enzymes.

Basic information

MOPS powder

In addition, MOPS also has the following characteristics common to Good's buffer system:

1. The pKa value is between 6-8;

2. High solubility in water;

3. It is not easy to penetrate the biofilm;

4. The salt effect is small;

5. Ion concentration, solution composition and temperature have little effect on dissociation;

6. Does not form complexes or precipitates with metal ions;

7. The buffer is chemically stable;

8. For the absorption of 0.1mol·L aqueous solution in the ultraviolet region, the absorbance at 260 and 280nm wavelengths is as small as possible;

9. Easy to make high-purity salt.

Application: MOPS buffer pKa: 7.2, pH range: 6.5-7.9, commonly used in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. It is suitable for electron transfer and phosphorylation studies of chloroplast thin-layer preparation; it can be formulated into a variety of agar media and used as a non-toxic buffer in the minimal medium for the cultivation of Streptomyces coryneformis and the production of cephalosporins; The electrolyte system component of two-dimensional gel electrophoresis isoelectric focusing electrophoresis (IEF); it can also be used in Northern hybridization as a buffer for RNA separation and transfer membrane.

Product packaging

Note: If the amount used each time is small, it can be used after appropriate packaging; the buffer will turn yellow when exposed to light, light yellow is completely usable, and it is not suitable to use after the color is too dark. Attention should be paid during use. For safety and health, please wear laboratory clothes and disposable gloves. If you accidentally contact your eyes, rinse immediately with plenty of water and seek medical attention.
