SPE Dry 96 Sample Concentrator System evaporates microplate samples by delivering heated gas above and below each well. Samples are quickly evaporated accurate temperature control is maintained.
BD Knockout RNAi Clone & Confirm PCR Kits generate candidate shRNA expression cassettes (SECs) precloned into vectors in as little as 4.5 hours. A single round of PCR is needed to generate an SEC suitable for functional testing.
Securline Universal Markers are for use in all hospital or laboratory departments. The versatile, all-purpose marker writes on central supply wrap, tape, plastic, glass, metal, porcelain, and foam. Information cannot be removed or smeared by autoclaving.
Investigator Raman-based spectroscopy system (CEM Corp.) provides an integrated approach for real-time reaction monitoring in a CEM microwave-enhanced synthesis system.
Biowave Spectrophotometer is a simple instrument for those in molecular biology/biotech disciplines who are working with DNA or proteins derived from bacteria or yeast's, and has four preprogrammed DNA concentration programs, as well as five for proteins.
Acura® digital micropipettes can be autoclaved fully assembled at 121 C, without requiring recalibration. The line features fixed volume Acura 815 models from 1 μl to 10 ml, adjustable volume Acura 825 models covering 0.1 to 1000 μl range, 2 macropipette Acura 835s for 0.
Measurements at high absorbance are among the most demanding tasks for a UV-visible spectrophotometer, with factors such as instrument linearity, stray light, and detector noise all conspiring to introduce potential errors. This situation is exacerbated when very small samples are being measured.
APOGEE automated peptide synthesizer enables both novice and expert peptide chemists to prepare long peptides of high quality as well as short sequences. Bar-coded, prefilled amino acid vials and optimized preprogrammed protocols facilitate error-free synthesis.
Non-antibody cartilage oligomeric matrix protein (COMP) fused to CD40 blocks CD40L-meditated proliferation of B-cells. Shown to display affinity for its ligand, CD40:COMP does not require any crosslinking reagent to effectively bind CD40L (CD154).
by Don Monroe, PhD Beyond Genomics Inc., Waltham, Mass., concluded separate drug discovery and development agreements with two major pharmaceutical firms within the last several weeks.
Small interfering RNAs (siRNAs) are a powerful tool for RNA interference (RNAi) experiments used to down regulate specific gene expression, with hundreds of papers now published each month.
Cobalt-based Protein Purification Resin Does Not Bind E. coli SlyD, A Common Contaminant in Ni-NTA IMACFebruary 9, 2004 7:21 am | Articles | Comments
E. coli SlyD, a prolyl isomerase, specifically binds divalent metal ions, which can result in significant contamination of IMAC preparations of heterologously expressed His-tagged proteins.
Compact refrigerated centrifuge 5702 R has a maximum speed of 3000 × g and offers a choice of fixed-angle or swing-bucket rotor. Round bottom and conical tubes from 1.1 ml to 85 ml can be centrifuged, as can 20 × 10 ml blood tubes, or 30 × 15 ml conical tubes.
Watson-Marlow Bredel 500 Series peristaltic pumps provide sterility and zero contamination. PumpSil Platinum Cured Silicone tubing further enhances the fermentation process and offers improved batch consistency.
UV PCR Workstation brings together UV light and antimicrobial stainless steel to create a protective environment against PCR contamination. The unit's chamber can be decontaminated between procedures with high intensity shortwave 254 nm UV.
