Trypsin/Lys-C Mix, Mass Spec Grade, is a mixture of Trypsin Gold, Mass Spectrometry Grade, and rLys-C, Mass Spec Grade. The Trypsin/Lys-C Mix is designed to improve digestion of proteins or protein mixtures in solution.   Using the conventional trypsin digestion protocol (i.e., overnight incubation at nondenaturing conditions), Trypsin/Lys-C Mix improves protein digestion by eliminating the majority of missed cleavages,…

Positive Pressure Manifold - A simple, robust way to quickly process up to 48 samples at one time. The Positive Pressure Manifold can accommodate a multitude of column sizes and provides even flow to each position. Positive Pressure Manifold Features: All 48 positions are individually regulated to provide even pressure to each column. There are four banks of 12 positions each. The user can control flow to each of the four…

500 g, cation exchange resin, sodium form, 1% crosslinkage, 50–100 dry mesh size, 300–1,180 µm wet bead size, ~3,500 MW limit

Positive pressure 96-well plate sample processing with Presston 1000 offers an advanced alternative to traditional vacuum manifold processing. To offer a wider applicability, Presston 1000 is equipped for processing samples in both a low pressure setting for typical solid phase extraction steps and a high pressure setting for very viscous sample processing and for sample dry down.  In addition, Presston 1000 is compatible with…

Beads containing sufficient covalently-linked Protein A for a binding capacity of 20+/-2 milligrams human IgG per 1 milliliter.

4 mm syringe filter with a Hydrophilic PVDF membrane, for non-sterile filtration, has a 0.22 µm pore size used in fine particle removal from aqueous & mild organic solutions.

GFP -Trap® - use your fluorescence fusion as tag for biochemical studies.Curiously GFP, the most widely used labeling tag in cell biology, is rarely used for biochemical analyses. This may be due in part to limited GFP antibody availability and specificity as well as co-eluted heavy and light antibody chains that interfere with subsequent analyses.Our GFP-Trap® is a high quality GFP-binding protein coupled to a monovalent matr…

For highly efficient total protein extraction from cultured mammalian cells. The complete cell lysis reagent is a nondenaturing detergent formulation that dissolves cell membranes and extracts total soluble cellular protein in only 5 minutes. M-PER Reagent requires little or no mechanical disruption and yields more protein than freeze/thaw cycles and sonication.This mammalian cell lysis reagent is so efficient that adherent c…

Agilent Bio-Monolith Protein A and Protein G LC columns are designed for analytical separation of all IgG subclasses (human and mouse). They deliver fast and accurate quantitation of mAb titer and purification of small amounts of mAb for further characterization.

Prepare concentrated nuclear extracts for an EMSA and gel shift assays. The Thermo Scientific NE-PER Nuclear and Cytoplasmic Extraction Kit provides for efficient cell lysis and extraction of separate cytoplasmic and nuclear protein fractions in less than two hours. The NE-PER Kit is a nuclear protein extraction method that involves simple, stepwise lysis of cells and centrifugal isolation of nuclear and cytoplasmic protein f…
