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
