Closures for containers and methods for using same are provided. In a general embodiment/the present disclosure provides a closure having a top portion (12), a bottom portion (14) and a side portion (16), an aperture (18) extending though the closure, a projection (20) extending from the closure and at least two rib members (36) on an interior of the projection. The projection may also include a cover (22). In another embodiment, a method for using a closure includes inserting a. spike member into a projection, piercing a membrane that hermetically seals a medical container, pushing rib members within the projection to center the spike member inserted into the projection, and tearing the membrane to create a vent hole in the membrane.
摘要:
The present invention describes a method for identifying one or more of a plurality of sequences differing by one or more single base changes, insertions, deletions, or translocations in a plurality of target nucleotide sequences. The method includes a ligation phase, a capture phase, and a detection phase. The ligation phase utilizes a ligation detection reaction between one oligonucleotide probe, which has a target sequence-specific portion and an addressable array-specific portion, and a second oligonucleotide probe, having a target sequence-specific portion and a detectable label. After the ligation phase, the capture phase is carried out by hybridizing the ligated oligonucleotide probes to a solid support with an array of immobilized capture oligonucleotides at least some of which are complementary to the addressable array-specific portion. Following completion of the capture phase, a detection phase is carried out to detect the labels of ligated oligonucleotide probes hybridized to the solid support.
摘要:
The present invention relates to a method for identifying a target nucleotide sequence. This method involves forming a ligation product on a target nucleotide sequence in a ligase detection reaction mixture, amplifying the ligation product to form an amplified ligation product in a polymerase chain reaction (PCR) mixture, detecting the amplified ligation product, and identifying the target nucleotide sequence. Such coupling of the ligase detection reaction and the polymerase chain reaction permits multiplex detection of nucleic acid sequence differences.

The ligation phase can be preceded by an amplification process. The present invention also relates to a kit for practicing this method, a method of forming arrays on solid supports, and the supports themselves.

The present invention is directed to a thermostable ligase having substantially higher fidelity than either T4 ligase or Thermus thermophilus ligase. The DNA molecule encoding this enzyme as well as expression systems and host cells containing it are also disclosed. The thermostable ligase of the present invention is useful in carrying out a ligase detection reaction process and a ligase chain reaction process.
摘要:
Ligase detection reaction is utilized to distinguish minority template in the presence of an excess of normal template with a thermostable ligase. This process can be carried out with a mutant ligase, thermostable ligase, or a modified oligonucleotide probe. This procedure is particularly useful for the detection of cancer-associated mutations. It has the advantage of providing a quantitative measure of the amount or ratio of minority template.
