The invention provides cell-permeable peptides that bind to JNK proteins and inhibit JNK-mediated effects in JNK-expressing cells. Each time when the locations of the probes and are moved, a received wave Gj is obtained. The method of synthesizing the conjugate is useful for labeling selected molecules, and the conjugates may be useful in diagnostic or therapeutic methods. The jack assembly is operable to otherwise displace the slide assembly along the guide member.
