Exclusion Chromatography Gel Permeation Chromatography

1979
In contrast to the separation techniques discussed up to now, separation by exclusion chromatography involves a single, unambiguous mechanism. In the absence of interactions (by definition) between the sample and the stationary phase surface, the elution order (or elution volume) is solely a function of the molecular size (see IX.B). Hence, this method

Gel‐Filtration Chromatography [PDF]

Current Protocols in Molecular Biology, 1998
AbstractGel filtration (GF) chromatography separates proteins solely on the basis of molecular size. Separation is achieved using a porous matrix to which the molecules, for steric reasons, have different degrees of access‐‐i.e., smaller molecules have greater access and larger molecules are excluded from the matrix. Hence, proteins are eluted from the

Reproducibility of gel‐chromatography

International Journal of Peptide and Protein Research, 1984
We think it worthwhile to other experimenters to mention the following observations. Recently it was noted that gel chromatographic separations of the five fragments resulting from the degradation of cytochrome c by bromocyanogen became dependent on the batch number of the gel. This dependency concerns only separations of unprotected fragments, using 7%

Gel chromatography of heparin

Journal of Chromatography B: Biomedical Sciences and Applications, 1981
It is assumed that heparin is a heterogeneous substance. In order to further investigate the purification of heparin, a column chromatographic technique for the fractionation of heparin is described using various diameters of bead form cross-linked dextran gels and an automated apparatus. It was observed that Sephadex G-50 resulted in the separation of

Resins and gels for chromatography

Journal of Chromatography A, 1970
Abstract Ion exchangers and gels for chromatography synthesized by the authors are decribed. Resins and gels for chromatography have been prepared based on copolymers of styrene and p - or m divinylbenzene. They are characterized by their high purity, homogeneity of granular composition, high mechanical strength and stability, and the ...
