    • A fastener (210) and a method for reducing wear on a driver blade in a fastening tool includes applying a layer of solid-based lubricant (216) between the head of a fastener and a driver blade end. The fastener is for use in a fastening tool and includes a head (214), a shank (212), and a Iayer of lubricant (216) on the head (214) of the fastener. The lubricant is graphite, molybdenum disulfide, tungsten disulfide, boron nitride, polytetrafluoroethylene (PTFE), nano-diamonds, calcium stearate, sodium stearate, oils, greases, waxes, thermoplastic polymers, or another lubricant that exhibits similar characteristics, Aromatic polyamides (such as Kevlar TM ), ultra-high molecular weight polyethylene, powdered glass, glass fibers, thermoplastic polymers, and thermoset polymers also are contemplate to provide a barrier to contact between the driver blade and fastener head. The lubricant is sprayed, rolled, brushed, blotted or otherwise applied between the head of the fastener and the driver blade end prior to firing the fastening tool.

    • The present invention is directed to a method for identifying one or more of a plurality of target nucleic acid molecules in a sample. This method includes providing a sample potentially containing one or more target nucleic acid molecules and a plurality of oligonucleotide probe sets. Each probe set is characterized by (a) a first oligonucleotide probe, having a target-specific portion and a tunable portion with an endcapped hairpin and (b) a second oligonucleotide probe having a target specific portion and a tunable portion. One of the first and second oligonucleotide probe has an acceptor group and the other of the first and second probe has a donor group. A ligase is provided and blended with the sample and the plurality of oligonucleotide probe sets to form a ligase detection reaction mixture. The mixture is subjected to one or more ligase detection reaction cycles with each cycle comprising a denaturation and hybridization treatment. During the denaturation treatment any hybridized oligonucleotides are separated from the target nucleic acid sequences, and, during the hybridization treatment, the set of oligonucleotide probes hybridize in a base-specific manner to their respective target nucleotide sequences, if present in the sample, and ligate to one another to form a ligation product. The ligation product contains the tunable portions, the endcapped hairpin, the target-specific portions, the acceptor group, and the donor group. The ligation products are subjected to conditions effective to permit hybridization of the tunable portions of the ligation product to one another to form an internally hybridized ligation product. The fluorescence resonance energy transfer (FRET) between the donor and acceptor groups of the internally hybridized ligation product is detected, thereby indicating the presence of a target nucleic acid molecule in the sample. An alternative embodiment of the present invention involves the use of an initial PCR amplification procedure with primers provided with universal tails. Finally, FRET detection can be carried out through the use of the above-described oligonucleotide probes without any ligation.
    • 本发明涉及用于鉴定样品中多个靶核酸分子中的一种或多种的方法。 该方法包括提供潜在地含有一个或多个靶核酸分子和多个寡核苷酸探针组的样品。 每个探针组的特征在于:(a)具有靶特异性部分的第一寡核苷酸探针和具有封端发夹的可调部分,和(b)具有目标特异部分和可调部分的第二寡核苷酸探针。 第一和第二寡核苷酸探针之一具有受体基团,第一和第二探针中的另一个具有供体基团。 提供连接酶并与样品和多个寡核苷酸探针组混合以形成连接酶检测反应混合物。 将混合物进行一个或多个连接酶检测反应循环,每个循环包含变性和杂交处理。 在变性处理期间,将任何杂交的寡核苷酸与靶核酸序列分离,并且在杂交处理期间,寡核苷酸探针组如果存在于样品中,则以碱基特异性方式与其各自的靶核苷酸序列杂交,并连接 彼此形成连接产物。 连接产物包含可调部分,封端的发夹,靶特异性部分,受体基团和供体基团。 连接产物经受有效的条件,允许连接产物的可调部分彼此杂交以形成内部杂交的连接产物。 检测内部杂交连接产物的供体和受体组之间的荧光共振能量转移(FRET),从而表明样品中存在靶核酸分子。 本发明的替代实施方案涉及使用具有通用尾部的引物的初始PCR扩增程序。 最后,可以通过使用上述寡核苷酸探针而不进行任何连接来进行FRET检测。
