this study was aimed at the evaluation of the influence of storage under various conditions on the relative concentrations of major protein fractions and their proportion in bovine serum. blood samples were taken from six dairy cattle of a low-land black spotted breed and its crossbreeds. the separated blood serum was fractioned into aliquots. one aliquot was analysed immediately after the sepa...

igd myeloma is very rate. it differs from multiple myeloma of other classes in several aspects and its laboratory diagnosis may be difficult, as total plasma protein concentration is often normal, and a paraprotein peak may not be easily demonstrable by the conventional electrophoretic techniques. we report here two cases of igd myeloma investigated in this laboratory. immunochemical, biochemic...

DOI: 10.1002/elps.202200230 The back cover picture shows a free-flow electrophoresis device separating and collecting different proteins. A novel velocity gradient is introduced across the chamber to counteract electrophoretic migration focus proteins at unique positions. There are several components overall profile that influence width of each protein stream, they deserve further investigation.

The separation of polypeptides by electrophoresis allowed Arne Tiselius to describe protein fractions corresponding to albumin, -, -, and -globulins in serum with the Rrst published diagram of human serum protein electrophoresis in 1939. The number of fractions slowly expanded into electrophoretic subfractions identiRed as 1, 2, 1, 2, 1 and 2. The mobility characteristics of these fractions are...
