Cytiva Amersham Pre-Packed DNA Purification Column, Amersham MicroSpin S-300 HR Format, Sephacryl S-300

Cytiva Amersham Pre-Packed DNA Purification Column, Amersham MicroSpin S-300 HR Format, Sephacryl S-300 HR Pre-Equilibrated Matrix/Construction, 25 to 50 uL Sample Vol, 4 deg C Storage Temp. MicroSpin S-300 HR spin columns for DNA purification from unincorporated primers (<20 mers) and nucleotides using spin-column chromatography in applications including desalting, buffer exchange and primer removal. MicroSpin columns are designed for rapid nucleic acid purification for use in a wide range of applications, including desalting, buffer exchange and primer removal. Good product yield and purity are obtained with sample Vols from 25 to 100 uL and from nanogram to milligram quanti-ties of DNA. MicroSpin S-200, S-300 and S-400 HR spin columns contain Sephacryl resin of differing pore sizes. They allow DNA purification via gel filtration. Molecules larger than the largest pores in the Sephacryl are excluded from the gel and elute first. Intermediate size molecules penetrate the matrix to varying extents, depending on their size and the resin used. Penetration of the matrix retards progress through the spin column, very small molecules elute last. The Vol required to elute these small molecules is dependent on the Vol available both inside and outside the pores, i.e. the bed Vol (Additional S&H or Hazmat Fees May Apply) - GHC-F
