title: [The electrophoretic properties of gels of high-resolution MS-4 agarose for separating DNA fragments in molecular genetic analysis].
abstract: The Hispanlab firm (Spain) offers a new series of Molecular Screen analytical agarose, including MS-4 agarose intended for separation of small fragments of DNA. This low-endosmotic agarose attracts attention as a probable alternative to well-known FMC Bio Products special agarose (USA) due to its useful properties. We characterized a gel-electrophoretic system based on MS-4 agarose (and its correspondence to its passport) and tested its fitness for standard molecular genetic expert investigations. The following parameters were assessed: mechanical properties of gel, its transparency, degree of background fluorescence upon ethidium bromide staining, resolving power, and position distortions in the electrophoregram. Important features of MS-4 agarose gels were detected, not typical of other agarose systems, which should be borne in mind during investigations with this agarose.
