A number of scientifically, and in particular medically interesting proteins can only be purified by time consuming routine methods, which require specific ligands
Vivascience recently extended its line of products to cover the rapid purification of proteins in biomedical and drug discovery applications with the following new membrane adsorber kits.
The new additions to the Vivapure range address one of the premier challenges in science: the separation of pure proteins from complex mixtures.
As is generally known, a number of scientifically, and in particular medically interesting proteins can only be purified by time consuming routine methods, all the more difficult as these often require much more specific ligands. For such proteins, the Vivapure epoxy protein coupling kit renders a highly selective affinity matrix that is tailor made for the given target protein.
Combined with the convenience of centrifugal devices, pure protein can be isolated in less than 30 minutes.
For the more rapid purification of antibodies, the Vivapure protein A mini spin columns were designed to combine the selectivity of membrane adsorbers with the speed and convenience of centrifugal devices.
Easily processed in parallel, these spin columns are ideally suited for screening for specific antibodies. Many recombinant proteins are over-expressed, carrying a tag of histidine residues.
In order to purify these fusion proteins, metal ion matrices are routinely used to capture the tagged proteins.
However, biodiversity has it that not all fusion proteins are equal and bind to a given metal ion with the same affinity.
The new Vivapure metal chelate mini spin columns allow the scientist to optimise the purification procedure to the requirements of the desired protein.
The spin column format furthermore lends itself for a parallel approach and accelerated isolation of the pure protein.
New are also the Vivawell 96 well and Vivawell eight strip formats, which make the Vivascience ion exchange and metal chelate membrane adsorbers available in high throughput format ready for automated processing of larger numbers of samples.
Vivascience kits offer selective membrane adsorbers for rapid protein purification in convenient centrifugal devices at an attractive price.
