Abstract: A one-piece cable tie includes a locking head and an attached strap, the locking head being adapted to receive and selectively engage a portion of the strap when the tie is formed into a closed loop. The cable tie additionally includes an insert fastener formed onto the locking head that is sized and shaped to be retained within a rectangular slot formed in a panel. The insert fastener includes a pair of spaced apart, parallel arms which extend orthogonally away from an outer end wall of the locking head, a cross-member extending transversely across the free ends of the pair of arms and a pair of offset retention fingers. Each retention finger is connected at one end to the cross-member and is capable of being independently pivotally displaced along an arcuate path. As a result of the offset design of its retention fingers, the cable tie can be manufactured as a unitary plastic member using simplified and inexpensive molding techniques.

Abstract: A method is described for the detection of 5-methylcytosine in genomic DNA samples. First, a genomic DNA from a DNA sample is chemically converted with a reagent, whereby 5-methylcytosine and cytosine react differently. Then the pretreated DNA is amplified with the use of a polymerase with primers of different sequence. In the next step, the amplified genomic DNA is hybridized to an oligonucleotide array and PCR products are obtained, which must be provided with a label. Alternatively, the PCR products can be extended in a primer extension reaction, wherein the extension products are also provided with a label. In the last step, the extended oligonucleotides are investigated for the presence of the label.
