Easy Estimation

The dotMETRIC protein and nucleic acid assays from Geno Technology Inc. of St. Louis make estimating protein and nucleic acid concentration simple and quick, with no expensive equipment. To estimate protein concentration, 1 µl of protein solution is mixed with the supplied dilution buffer and spotted onto a test strip. The resultant spot diameter is proportional to the concentration of the sample. The assay takes only eight to 10 minutes to perform and can detect as little as 2 ng of protein. The NUCLEIC dotMETRIC assay kit uses the same principle to detect small quantities of DNA, RNA, and oligonucleotides in solution in only two minutes. The kits, which contain an easy-to-use dotMETRIC application device and enough reagent for more than 300 assays, have a list price of $145.00.

Diversified Biotech's Well Orienter

Well, Well, Well

Working with samples in microplates has never been easier with the Well Orienter, Pad, and Stand from Diversified Biotech of Boston. The Well Orienter, a plastic card that fits under a 24-, 48-, or 96-well plate, uses sharp, alphanumeric characters to label each sample, providing easy cross-referencing. The handy Well Stand tilts a plate at a 30° angle for comfortable pipetting and label reading. For convenient documentation, each sheet of the Well Pad is preprinted to look like a 96-well plate and is adhesive to allow easy affixing in a lab notebook. The list price for a pack of four Well Organizers is $25.00, a Well Stand is $25.00, and Well Pads are $10.00 each.
