38 years of experience in the manufacturing of IEF carrier ampholytes, e.g. Sepalytes and GelStick PAG film, and sustained efforts to optimise IEF separation performance have led to the new product we call
ProPhyl Air Gel Matrix
 |
–NEW–
|
 |
ProPhyl Air is a new type of gel matrix with unusual physical properties which, in combination with our self-produced carrier ampholyte (Sepalytes), represents an excellent resolution of native protein mixtures in isoelectric focusing. ProPhyl Air improves the solubility of proteins because it carries charged groups. This not only affects entry of proteins into the gel but also prevent precipitation near the isoelectric point, which gives rise to sharper bands in general and also more bands.
Its use could therefore be revolutionary for those working with a wide range of proteins
To convince you of the excellent separation properties of ProPhyl Air, simply send us your native protein samples.
Within 2-4 days we will send you the results at no cost!

Future Outlook
With the help of ProPhyl Air it is now possible to discover native proteins that were previously undetectable with the conventional acrylamide gel matrix used worldwide for 60 years. Examples of such proteins are biomarkers for cancer, Parkinson’s disease (PD), Alzheimer’s (AD), and EPO. ProPhyl Air also exceeds the capabilities of the IPG matrix (2D electrophoresis) in certain areas, e.g. membrane proteins, because of excellent protein solubility in the gel matrix and superior performance in the first dimension of 2D. With ProPhyl Air, many proteins previously thought to be poorly soluble may no longer need detergents such as CHAPS, triton X-100 or NP-40. The use of denaturing 8M urea, which can falsify results in many ways, could thus become a thing of the past. |
In some cases it is even possible to do detection without antibodies (immunoblotting). The entire 2D ProPhyl Air electrophoresis process (with ampholytes, e.g. Sepalytes), including the pouring of gels (IEF / SDS) is completed in less than 4 hours, since a rehydration time of up to 12 hours and 8 hours of electrophoresis (IEF), as required with the ready-to-use IPG strips/gels is not necessary anymore. In addition, the current IPG strips/gels manufactured by various companies are rigid and therefore restrictive, since they allow the researcher no scope for variation of the cross linking of the IEF matrix (%T,%C). The comparative advantages of the new ProPhyl Air gel matrix are its speed and flexibility. |
