96-well Filter Spin Plates For Protein Purification



High-throughput protein purification is commonly performed on E. coli cultures expressing a fusion protein that are grown in 96-well deep-well plates. These small cultures (~1mL) are ideal for expressing a library of cDNAs or to generate a series of variants for a particular protein to perform mutational analysis. Because 96-well spin plates are compatible with automated liquid handling systems or properly equipped centrifuges, immobilized metal affinity chromatography (IMAC) and other fusion tag affinity resins can be integrated into high-throughput protein purification workflows.

In addition, using an optimized cell lysis reagent, such as Thermo Scientific B-PER Direct Bacterial Protein Extraction Kit (Part No. 90080), the cultured cells can be lysed directly in their growth media and applied to the filter plate affinity resin, eliminating the need to centrifuge and aspirate these types of cultures prior to processing.

The following Thermo Scientific Pierce 96-well Spin Plates are available for fusion protein purification:

HisPur Cobalt Spin Plates

Thermo Scientific HisPur Cobalt Spin Plates use cobalt ions immobilized onto a 6% agarose resin with a tetradentate chelator and have been optimized for high-purity 6xHis-tagged protein purification. Immobilized cobalt exists as a divalent cation and associates with histidine amino acid side chains for the selective enrichment of His-tagged proteins. Elution is performed with an excess of imidazole.

96-well Spin Balance Plate

HisPur Cobalt Spin Plates Thermo Scientific HisPur Cobalt Resin delivers high-purity His-tagged protein purification. Bacterial lysate (4mg total protein) containing over-expressed recombinant 6xHis-tagged GFP was prepared in B-PER Bacterial Protein Extraction Reagent (Part No. 78243) and applied to each well of a HisPur Cobalt 96-well Spin Plate. The flow-through and pooled elution fractions were visualized on an SDS-PAGE gel stained with GelCode Blue Stain Reagent (Part No. 24590). Approximately 1mg of His-tagged protein was recovered per well with 87% purity, as determined by densitometry. Protein concentrations were determined by Coomassie Plus Protein Assay (Part No. 23238). M = MW marker, L = lysate, F = flow-through, E = eluate.

HisPur Ni-NTA Spin Plates

Thermo Scientific HisPur Ni-NTA Spin Plates use nickel ions immobilized onto a 6% agarose resin with nitrilotriacetic acid (NTA) chelator and is the most commonly used IMAC resin due to its high binding capacity (60mg His-tagged protein/mL of resin).

The purity of the samples in lanes 6 to 8 was 90%, as determined by densitometry. M = MW marker, L = lysate, F = flow-through, W = wash, E = eluate.

Pierce Glutathione Spin Plates

Thermo Scientific Pierce Glutathione Spin Plates use a glutathione tripeptide (GSH) immobilized on a 6% crosslinked agarose. The GSH ligand is specific for glutathione-S-transferase (GST), and the immobilized glutathione agarose used in these spin plates can purify up to 10mg of GST-fusion protein per milliliter of resin.
