What is the pH range of 3- (Cyclohexy-Lamine) -1-Propanesulfonic Acid CAPS Buffer?
The suitable pH range of 3- (cyclohexylamine) -1 -propanesulfonic acid (CAPS) buffer is about pH 9.7 to 11.1. This buffer has a wide range of uses in biochemical experiments, and its acid-base properties make it effective in maintaining the pH stability of the solution in this pH range.
In experiments such as protein electrophoresis, if a high pH environment is required to ensure that the protein is in a specific charge state, maintain structural stability, or promote specific reactions, CAPS buffer is extremely suitable. Because this pH range can provide a stable chemical environment, reduce the influence of external factors on the sample, and make the experimental results more reliable.
For example, when studying protein activity under alkaline conditions, the pH 10.5 environment of the CAPS buffer can simulate specific physiological or reaction conditions to ensure that the protein is at an appropriate pH level, so that the study can accurately observe its activity changes.
If some enzymatic reactions are carried out, when the reaction needs to be in a high pH environment to achieve the best catalytic efficiency, the applicable pH range of the CAPS buffer can meet the needs. By blending to a suitable pH value, the enzyme activity can be ensured to play out normally, and the experiment can be carried out smoothly.

3- (Cyclohexy-Lamine) -1-Propanesulfonic Acid CAPS Buffer How to configure
To prepare 3 - (cyclohexylamino) -1 -propanesulfonic acid (CAPS) buffer, you can do it according to the following method.
Prepare the required reagents and utensils first. The reagents need CAPS solute, appropriate acid-base regulator (such as hydrochloric acid, sodium hydroxide), and the utensils should have a precision balance, volumetric flask, glass rod, pH meter, etc.
Take the preparation of CAPS buffer with a certain concentration and pH value as an example. If you want to make 1L of CAPS buffer with 0.1mol/L and pH 10.0, first weigh an appropriate amount of CAPS solute with a balance. According to its molar mass, 0.1mol/L × 1L needs to be weighed and placed in a beaker. Add an appropriate amount of deionized water and stir with a glass rod to help dissolve. After
, transfer this solution to a 1L volumetric flask, rinse the beaker several times with a small amount of deionized water, and then add deionized water to the scale line.
Next, monitor with a pH meter and slowly adjust the pH with an acid-base regulator. If the pH is low, add sodium hydroxide solution dropwise; if the pH is high, add hydrochloric acid solution dropwise to pH 10.0. Finally, bandwidth evaluation to the scale line, shake well to obtain the required CAPS buffer. During the process, pay attention to the operating specifications to ensure the accuracy and reliability of the buffer.
How stable is the 3- (Cyclohexy-Lamine) -1-Propanesulfonic Acid CAPS Buffer?
3 - (hexylamine) -1 -propanesulfonic acid (CAPS) liquid is of high quality. This liquid can be stored for a short time under normal conditions, and its properties can still be maintained. However, if you want to survive for a long time, you need to be cautious.
Under normal circumstances, if the CAPS liquid is stored in the room for 7 days, its pH value and chemistry may not change. However, if the environment is too high and the storage is too high, some components in the liquid may be accelerated due to the reaction, causing its equilibrium to change, and its quality will also be reduced.
Furthermore, light also affects its quality. If the CAPS liquid is exposed to light, or it may cause photochemical reactions, it will break the original transformation of the liquid and affect its performance.
To maintain good quality of the CAPS liquid, it is recommended to store it in a warehouse and protected from light. If it needs to be stored for a long time, it can be refrigerated, generally at 2-8 ° C. In this way, it can effectively extend its storage time, ensure that it is in use, and can maintain good performance to meet the needs of each warehouse or project.
What is the effect of 3- (Cyclohexy-Lamine) -1-Propanesulfonic Acid CAPS Buffer on biomolecules?
3- (hexylamine) -1-propanesulfonic acid (CAPS) solution is used in the study of biomolecular effects. The pH effect of the solution is 9.7-11.1, which is used for the study of specific biomolecules such as lyophilic enzymes.
On the protein surface, due to its specific pH environment, it can effectively maintain protein stability and prevent protein stability. For example, in some protein purification processes that require high pH environment, the CAPS solution can maintain the integrity of the protein, ensuring that its activity is not lost.
In the field of nucleic acid research, high pH environment may affect the effect of nucleic acid groups. The properties provided by CAPS solution may promote DNA differentiation. This property is very important for specific nucleic acid analysis techniques, such as coagulation, etc., and researchers can use it to explore the properties of nucleic acids.
In addition, CAPS solution does not react to many biological molecules due to its chemical properties. Therefore, in biological analysis techniques such as immunoassay and enzyme immunosorbent assay (ELISA), it can also be used to ensure that the specific properties of biomolecules are not dried and improve the sensitivity. Therefore, CAPS solution plays an indispensable role in many aspects of biomolecular research according to its specific pH and chemical characterization.
