    摘要： The invention is directed to a Method for detecting a target moiety in a sample of biological specimens by: a) providing at least one conjugate with the general formula (I) An-P-Bm-Cq-Xo  (I)  with A: antigen recognizing moiety; P: enzymatically degradable spacer; B: first binding moiety C second binding moiety X: detection moiety; n, m, q, o integers between 1 and 100, wherein B and C are non-covalently bound to each other and A and B are covalently bound to P b) labelling the target moiety recognized by the antigen recognizing moiety A with at least one conjugate c) detecting the labelled target moiety via detecting moiety X d) cleaving Cq-Xo by disrupting the non-covalent bond between Bm and Cq from the labelled target moiety e) cleaving the binding moiety Bm from the labelled target moiety by enzymatically degrading spacer P. The method is useful to identify target moieties on the biological specimens. The biological specimens detected by the conjugate can be subsequently removed from the sample.

    摘要： The present invention provides a method for polyclonal stimulation of T cells, the method comprising contacting a population of T cells with a nanomatrix, the nanomatrix comprising a) a matrix of mobile polymer chains, and b) attached to said matrix of mobile polymer chains one or more stimulatory agents which provide activation signals to the T cells; thereby activating and inducing the T cells to proliferate; wherein the nanomatrix is 1 to 500 nm in size. At least one first and one second stimulatory agents are attached to the same or to separate mobile matrices. If the stimulatory agents are attached to separate nanomatrices, fine-tuning of nanomatrices for the stimulation of the T cells is possible. Closed cell culture systems also benefit from this method.
