  • Tube rack tool
    Patent number: 9802200
    Abstract: Tools and methods are provided for removing a plurality of tubes from a rack of tubes. Tube rack tools include a base and/or top piece for receiving the rack of tubes. The base has a support surface for engaging the closed bottom of the plurality of tubes. The support surface can be curved such that the rack of tubes can be rocked about the curves support surface to dislodge the plurality of tubes from the rack. The top piece can be configured to engage the rack such that pressure on the top piece in the direction of the support surface applies a pressure on the rack without applying the pressure to the tubes. The tubes are dislodged from the rack by application of the pressure. Elements of the tube rack tool are also configured for securing the tubes within the rack or caps to the tubes.

  • Primers for melting analysis
    Patent number: 9771610
    Abstract: Methods and kits are provided for nucleic acid analysis. In an illustrative method a target nucleic acid is amplified using a first primer and a second primer, wherein the first primer comprises a probe element specific for a locus of the target nucleic acid and a template-specific primer region, and the probe element is 5? of the template-specific primer region, subsequently allowing the probe element to hybridize to the locus to form a hairpin, generating a melting curve for the probe element by measuring fluorescence from a dsDNA binding dye as the mixture is heated, wherein the dye is not covalently bound to the first primer, and analyzing the shape of the melting curve. Kits may include one or more of the first and second primers, the dsDNA binding dye, a polymerase, and dNTPs.
