Smaller pore size packings (pore size 80 to 120Å) are best for small molecules with molecular weights up to a molecular weight of 2000. For larger molecules with MW over 2000, wider pore packings are required; for example, a popular pore size for proteins is 300Å.

Size Exclusion Columns. Size exclusion spin columns are an invaluable tool for purifying and separating nucleic acids or proteins. They can be used to prep DNA, RNA or protein samples for many protocols, particularly those involving PCR, sequencing, or protein recovery. Spin columns can be used for basic prep steps like desalting or buffer..

Spin Columns-Snap Cap with Collection Tubes (Part No. 69725): Column volume: 1000μL; Resin volume: 20 to 500μL; Filter type: polyethylene filter, 30μm (20 to 50μm) pore size; Cap type: snap cap on column (no cap on collection tube); press-on bottom caps; Micro-Spin Columns (Part No. 89879): Column volume: 400μL; Resin volume: 5 to 100μL. Annealing spin-cast thin (65 nm) ﬁlms intensiﬁes this reﬂection but does not otherwise alter the spectrum [162]. Debye-Scherrer analysis determined that mean crystallite size was largest after short annealing (5 min) at 125 C - suggesting a relation with Tg2. The ﬁnal structure is solvent dependent.

O Mini: 600µl o Midi: 20 ml Maximum g force: o Mini: 12-14,000 x g o Midi: 1,500 x g Typical Spin Times: o Mini: 30 seconds - 1 minute for up to 0.6 ml sample at 12-14,000 x g o Midi: 5 min for up to 20 ml sample at 750 x g. STORAGE CONDITIONS. Columns are shipped under ambient temperature. For a monoclonal antibody (mAb), the size of the molecule is around 5 nm. If you are trying to separate a mAb monomer from its aggregates (dimer, trimer, and higher-order species), the largest molecule could be approaching 10 nm in size. The most appropriate pore size column for this separation is therefore 30 nm, or 300 Å. Pierce C18 Spin Columns and Spin Tips effectively remove interfering contaminants while maintaining excellent binding and recovery of peptide samples for use upstream of mass spectrometry and other high... 50 Columns: Unit Size: 50 columns: Add to cart.
