Presidential DNA sheds light on ancestry
02 April, 2007Research into the ancestry of US President, Thomas Jefferson has thrown new light onto his ancestry and the migration of a rare class of DNA.
Sub-microlitre DNA analysis
12 January, 2007Designed for use with several Thermo UV/vis spectrophotometers, including the Spectronic BioMate 3, the Spectronic Genesys 10 Bio, and the Evolution 300, the nanoCell accessory offers sub-microlitre analysis capabilities for DNA and protein analysis in the life science laboratory. The nanoCell allows users to obtain the maximum amount of information from minute sample volumes. This is especially critical in laboratories performing assays for nucleic acids, RNA/DNA and protein concentrations that wish to limit the amount of sample used for analysis.
Application to characterise structure of DNA molecules
03 March, 2006An application to enable more precise measurement of the location of a fluorescent label in a DNA layer has been developed by a team of researchers from Boston University in the US.
RNAi services
02 February, 2006Invitrogen and genOway have signed a co-marketing agreement around RNAi related services. Under the terms of the agreement, Invitrogen and genOway will combine Invitrogen's expertise in RNAi research technologies with genOway's portfolio of transgenesis technologies and RNAi in vivo experience to create a services platform offering RNAi vector design through the creation of RNAi transgenic rodent models.
DNA separation
16 January, 2006Cambrex's FlashGel System can be used to separate DNA in 2-7 mins while monitoring migration in real time on the bench under normal laboratory light conditions (no harmful UV illumination).
GeneFlash USB gel documentation system
08 December, 2005Syngene has introduced the GeneFlash USB, claimed to be the first gel documentation system on the market to use USB memory device technology to accurately record gel images that are both PC and Mac compatible.
Nucleic acid extraction from blood
14 September, 2005Fuji Photo Film has entered the market for nucleic acid extraction with the QuickGene-810. It consists of a compact, space-saving tabletop device (40 x 45 cm) and matching kits for extraction of DNA and RNA. Using this system, DNA can be obtained from whole blood in just six minutes (for eight samples).
RNAi libraries
10 August, 2005Sigma-Aldrich has introduced the Mission RNAi product line, including the first available formats for the RNAi Consortium (TRC) shRNA libraries.
Nucleic acid purification
13 May, 2005Invitrogen supplies a full range of products for nucleic acid purification - including DNA, RNA and fragment purification and purification/clean-up - for basic research clinical diagnostic, forensic or other needs.
Fast DNA extraction
16 August, 2004Sigma-Aldrich has introduced a tissue PCR kit that contains reagents to rapidly extract genomic DNA from tissue or cells and amplify targets of interest by PCR. Extract-N-Amp Tissue PCR kit (Product number XNAT) offers a single-step extraction of tissue genomic DNA in less than 15 minutes.
De novo sequencing of tryptic peptides
08 May, 2003De novo sequencing has evolved to become a very useful tool for the complete elucidation of protein primary structures - especially in case of an unknown proteome. In a recent contest, MALDI-TOF/TOF MS has shown its huge potential for this task
DNA transcription is tuned to specific cells
08 November, 2001Researchers have found a new example of how the machinery that controls the transcription of DNA to messenger RNA (mRNA) is tailored to specific cells or genes
