Cellulose 300 PEI, polyester backed TLC plates contain fibrous cellulose impregnated with polyethyleneimine. The coating thickness is 100um and dimensions are 20x20cm. There are 25 plates per pack. Applications include: analysis of nucleic acids, and of mutagenic substances with the 32P post-labelling procedure (see Sorbtech Application No. 402260.) Cellulose ion exchange layers are suited for the separation of substances with exchange-active groups. Consequently they are used for the separation of amino acids, peptides, enzymes, nucleic acid constituents (nucleotides, nucleosides) etc. PEI is not a chemically modified cellulose, but a complex of cellulose and poly- ethyleneimine. PEI cellulose is a relatively strong anion exchanger. PEI layers should be stored in a refrigerator at 4C. An important application of CEL 300 PEI is the analysis of mutagenic substances with a 32P postlabelling procedure.
