An Electrophoresis Apparatus for analysing Several Sera Simultaneously

Maximizing Several Cuts Simultaneously

Consider two graphs G1 and G2 on the same vertex set V and suppose that Gi has mi edges. Then there is a bipartition of V into two classes A and B so that for both i = 1, 2 we have eGi(A,B) ≥ mi/2 − √ mi. This answers a question of Bollobás and Scott. We also prove results about partitions into more than two vertex classes.

A new apparatus for preparative gel electrophoresis.

paratus is the dimension of the elution cham ber; if a large chamber is employed, dilution of solute occurs thus resulting in broadening of the elution patterns, while with a narrow chamber elution is frequently interrupted by the swelling of gel during operation. In many cases, either upward or downward elution has been employed and this leads to com plication of the apparatus. This communi ca...

A convenient apparatus for vertical gel electrophoresis.

‘T1HE INTRODUC”ION of starch gel as an electrophoresis medimn by Smithies k4) arkecl a significant advance in the analysis of serum proteins. The increased resolving power afforded by this medium is indicated by the fact that as many as 30 distinct components can be electrophoretically separated; only 5 or 6 are usually observed on paper or in free-solution electrophoresis. Acrylamide gel (2, 3...

A Simpler and Faster Version of Two-Dimensional Gel Electrophoresis Using Vertical, Mini SDS-PAGE Apparatus

We have modified one of the most useful methods of protein separation; namely, two dimensional gel electrophoresis (2-DE). This modified version of 2-DE is not only simpler and easier but also faster than all the currently available methods. In this method, isoelectric focusing is carried out in the first dimension using a vertical sodium dodecyl sulfate polyacrylamide gel electrop...
