BIOTRANS PVDF membrane sheet
Biotrans PVDF membranes are naturally hydrophobic polyvinylidene difluoride membrane developed for use in protein transfer and immobilization procedures. The Biotrans PVDF membrane is a pure white microporous solid phase support which undergoes strong hydrophobic interaction with a wide range of proteins. Immobilized proteins can be used directly for protein .Immobilized proteins can be used directly for protein sequencing or amino acid analysis, and can be visually detected with all common staining reagents, including coomassie blue, amido black, ponceau S, and colloidal gold.
BIOTRANS (+) tranfer membrane
BIOTRANS (+) has a pore surface populated by a high density of quarterly ammonium groups which make it strongly cationic. The positive surface charge is maintained in the range pH 3 to over pH 10 and promotes strong ionic binding of negatively charged proteins and nucleic acids. BIOTRANS (+) membrane is ideally suited to new rapid transfer techniques for nucleic acid which provide excellent levels of sensitivity (e.g. Alkaline Transfer Procedure ). In addition, the membrane's immediate immobilization characteristics make it suitable for prolonged transfer procedures without the risk of nucleic acid diffusion from the membrane.
