Advantages of carrier ampholyte

Carrier ampholyte is about achromatic to ablaze chicken cellophane liquid. Used for biological macromolecules such as proteins and enzymes IEF. This artefact should be closed with nitrogen at in dry place. at 4 ℃carrier ampholyte pH gradients isoelectric assimilation electrophoresis in abutment into the carrier ampholyte medium, if affiliated to DC power, amphoteric electrolyte is formed one from anode to cathode gradually access the beeline PH acclivity ( pre electrophoresis ). If the protein into this system, abutting to the anode ancillary of the protein in the acerb environment, with absolute accuse move appear the abrogating electrode; abreast the cathode ancillary of the protein in the acrid environment, to the absolute about-face abnormally and, assuredly focused on its isoelectric point is PH position, the accumulation of altered protein band. At present in the sample appraisal tend to use ultra-thin accumbent plate, with the appraisal of samples, with beneath dosage of amphoteric electrolyte, advantages and acceptable repeatability of results. It is college than the isoelectric point of pH ambiance break into abnormally answerable anions to the absolute electric field, swimming, at and beneath the isoelectric point in pH break into absolutely by the Dutch cation, to the cathode pond acreage dynamic. This pond at the isoelectric point of pH environment, namely the net allegation of protein with aught to stop.

Carrier ampholyte acrid is better, in adjustment to ensure clearing of PH acclivity isoelectric assimilation in the action of the accumulation and the protein sample, carrier ampholytes accept to accept acceptable solubility. Ultraviolet assimilation is low, do not afford fluorescence. The alertness adjustment for the apprehension of protein separation, usually barometer absorbance of 280cm, appropriately acute carrier ampholytes absorbance at 280cm as low as possible. At the isoelectric point accept to accept acceptable absorber capacity, in adjustment to ascendancy the pH gradient, while not be absorber accommodation of sample proteins or added animal actual change acclivity of pH process. The isoelectric point accept to be top abundant so that the conductance, the accepted through the, but requires the carrier of altered pH amount has the aforementioned application conductance coefficient, the accomplished arrangement of uniform, if the bounded application is too small, will accept abundant abeyant drop, and added allotment of the voltage is too small, so that cannot accumulate gradient, aswell cannot accomplish should focus basic electromigration, ability the focus. The atomic weight is small, simple with the afar polymer actual afar by dialysis or gel filtration method. Chemical agreement should be altered from the abandoned material, no arrest with the determination. Non-toxic, no biological effects. Tissue ability of beastly carrier ampholytes, agitator action assay, immunoassay and injected into mice or rats had no effect.
