Hemoglobin detected ief
IEF involves adding an ampholyte solution into immobilized pH gradient (IPG) gels. IPGs are the acrylamide gel matrix co-polymerized with the pH gradient, which result in completely stable gradients except the most alkaline (>12) pH values. The immobilized pH gradient is obtained by the continuous change in the ratio of immobilines. An immobiline is a weak acid or base defined by its pK value. WebHb G-Philadelphia from Hb S is achieved. Hb Barts may be clearly detected. The preparation and separation of hemoglobin is accomplished through the application of a hemolysate onto a precast agarose gel containing RESOLVE Ampholytes. RESOLVE Ampholytes are composed of low molecular weight amphoteric molecules with isoelectric …
