CHROMA SPIN Columns are spin columns packed with gel filtration
resin to rapidly purify and size select nucleic acid samples.
The columns can be used to purify single- or double-stranded DNA
or RNA from contaminants such as salts, solvents, enzymes, or
proteins. Molecules larger than the particular matrix pore size
are eluted out of the column while smaller molecules are
retained inside the column matrix. As a result, these columns
are ideal for size fractionation of libraries or for removal of
primers. Available in Three Different Sterile Buffers - TE
buffer: ideal for routine DNA applications - STE (0.1 M NaCl +
TE) buffer: used for applications requiring a higher salt
concentration to prevent ionic interaction between molecules -
DEPC-treated water (+ 0.1 mM EDTA): useful for RNA purification
and those applications requiring a completely nuclease-free
environment Choose from Six Column Pore Sizes CHROMA SPIN-10,
-30, -100, -200, -400, and -1000. All columns, matrices, and
buffers have been autoclaved to de
