Pre-poured agar plates for use in molecular biology are packaged sterile and offer consistency from lot-to-lot. The line will include LB and LB Ampicillin Agar, as well as custom plates covering a range of media formulations and antibiotics. Each lot of plates is tested with several E. coli strains.
Criterion dehydrated microbiology culture media is formulated for solubility and milled for consistency. The product is offered in four sizes – 2 ml Mylar zipper bag; 500 gm wide mouth bottle with finger grips; and 2 and 10 kg buckets.
A Human ACE Quantikine( ELISA kit is available from R&D Systems. Angiotensin I Converting Enzyme is known for its role in blood pressure control and water and salt metabolism. ACE is also involved in immunity, reproduction and neuropeptide regulation due to its localization and specificity.
ECIS Model 1600 (Electric Cell-substrate Impedance Sensing) measurement follows the impedance of cell-coated electrodes in real-time and is non-invasive and quantitative.
New 225 cm 2 NUNC EasYFlask is equipped with a system that allows opening or closing the flask by a mere one-third turn of the cap. Maximum airflow underneath the flask optimizes temperature equilibration during incubation, even when stacked.
Miltenyi Biotec has recently introduced the MACS basic media product line comprising RPMI and DMEM with classical formulations and modifications thereof with stable glutamine. RPMI and DMEM are used for a broad spectrum of applications.
Kimble and Kontes have upgraded all of their filter flasks, which now feature a heavier, more uniform bead for less chipping and maximum durability. Heavier walls mean less chance of breakage during vacuum filtration. Beaded bottoms increase scratch resistance.
Gibco Advanced D-MEM/F-12 and Advanced RPMI 1640 reduced serum media formulations enable researchers involved in mammalian cell culture to reduce Fetal Bovine Serum (FBS) supplementation by 50 to 90 percent with little or no change in cell growth, promotion, morphology or function.
New 384 well optical imaging microplate for high content screening is manufactured using a molding process that ensures flat well bottoms and well-to-well uniformity. The dimensional stability of this plate ensures that microscope refocusing is minimized for higher throughput imaging.
The entry-level Biomass Monitor Model 210 provides a real-time record of the viable cell concentration, allowing users to see those critical process events.
ATCC has introduced E. coli competent cells and SOC Medium for researchers who utilize transformation in the study of gene expression, cloning, and other applications. GC5 and GC10 cells consistently show transformation efficiencies of >10 9 , and are are resistant to lytic phages T1 and T5.
FiberCell® Systems Duet hollow fiber modules are offered for cell culture scale-up for antibody and recombinant protein production.
Imaging living samples of cells or other organisms in real time places new demands on the microscope, the chamber needed to support the sample and the microscopist. This article details recent efforts to answer the first two of these areas.
Highly purified water has become a standard tool in molecular biology. Techniques such as reverse osmosis, electrodeionization, ultrafiltration, and chemical treatments provide water of varying quality and utility. Water quality specifications differ for applications such as liquid chromatography, in situ hybridizations, single nucleotide polymorphism analysis, and DNA amplification.
