Sigma Aldrich Fine Chemicals Biosciences HisTrapTM fast flow Cytiva
HisTrap(TM) ff is a ready-to-use column prepacked with precharged Ni Sepharose(R) 6 fast flow for preparative purification of histidine-tagged recombinant proteins by immobilized metal ion affinity chromatography (IMAC).Ni Sepharose(R) 6 fast flow consists of 90 mum beads of highly cross-linked agarose to which a chelating ligand has been immobilized. This chelating ligand is charged with Ni2 ions the first-choice metal ion for purifying most histidine-tagged proteins. The negligible leakage of Ni2 ions from the matrix ensures reliable capture of histidine-tagged proteins in repeated IMAC purifications.The high flow rates made possible by the Ni Sepharose(R) 6 fast flow matrix make HisTrap(TM) ff columns well suited for small scale-up. Capacity can be increased by connecting columns in series. HiTrap(R) IMAC ff is the product of choice when charging the medium with different metal ions for optimization of purification protocols.

Sigma Aldrich Fine Chemicals Biosciences Roll SealTM sealing films1EA
Excel Scientific now offers adhesive sealing films on Roll-Seal rolls for use with high-throughput automated microplate sealers. Film rolls constructed on three-inch-diameter plastic cores are compatible with most common adhesive sealers (Brandel Thermo-Fisher/Abgene FluidX KBiosystems). The Roll-Seal format provides reliable and efficient sealing at a lower cost per plate with minimal user intervention. Robust static-free packaging provides protection during shipment and facilitates accurate alignment and adhesion.Fast efficient high-throughput sealing 2.5-5 seconds/plate no handling and backing removal from individual sheetsHands-free reduces chance of mishap or contamination more uniform sealing from plate-to-plateHeat-free no high temperatures to damage sensitive samples or warp plates and cause robotic handling problemsEspecially convenient when working with foils avoids curling that occurs with individual sheetsEconomical lower cost per plate than
