B. Use a syringe to do this. Higher concentrations reduce column resolution and give lower yield due to increased viscosity. Today, DNA oligonucleotides are foundational for genetics and genomics, where they are used for amplification, enrichment, detection, and sequencing techniques [2–5]. Make sure your samples contain enough salt before using the NucleoBond® Finalizer kits. Intended use The illustra™ NAP™-25 Columns and components have been 4 Protocol for Glen Gel-Pak™ 2. Samples are pipetted into the spin column, and using centrifugation, are moved through a column matrix, where specific components of the sample bind to the membrane or resin within the column or are washed through. 7 volumes of isopropanol to solutions containing at least 0. Columns with a 6,000 Da size exclusion limit (globular proteins) are used for most applications. 2. The MicroSpin G-25 column is designed for the rapid purifica-tion of DNA for use in a wide range of applications, including desalting, buffer exchange, and removal of labeled nucleo-tides from DNA labeling reactions. 5–100 mL，快速去除低分子量化合物，适用于蛋白质脱盐和回收。赛默飞中国为您提供高质量的脱盐离心柱、脱盐板和脱盐纯化柱，欢迎咨询购买。了解更多详情，请访问赛默飞中国官网。赛默飞致力于提供卓越的产品和服务，满足您的科研需求。 Oct 5, 2021 · The take home message For desalting 1ng or 3pg of intact plasmid, commercial microcolumns gave superior transformation efficiencies compared with the other methods.

Disposable NAP DNA purification columns, prepacked with Sephadex G-25 DNA Grade. 5 mL samples of bovine serum albumin (BSA) at concentrations of 0. 3. The fractionation range for globular proteins is between M r 1000 and 5000, with an exclusion limit of approximately M r 5000. Mar 26, 2025 · 3. 5 mL Yield/recovery of DNA > 90% Purity of recovered DNA Typically < 3 % salt contamination Length of labeled For DNA purification: desalting, buffer exchange, removal of dye terminators from cycle sequencing and labelled nucleotides from DNA labelling reactions. Desalting columns feature different molecular weight cut-offs (MWCO) ranging from 18 kDa to 70 kDa, suitable for purifying proteins, nucleic acids, and other macromolecules. Desalting columns are available with a 40,000 Da size exclusion limit. The end result is that the larger molecules elute first in the column void volume while the small molecules are still flowing through the resin of the column.
