    摘要: The disclosure relates generally to the field of T-cell receptors or T-cell receptor mimics, and methods for obtaining novel T-cell receptors or novel T-cell receptor mimics. The compositions and methods described identify pairs of T-cell receptors and antigens. The compositions and methods allow high throughput analysis so that many antigens can be paired with a large repertoire of T-cell receptors.

    摘要: 【課題】本発明は、細胞による発現系に移行する前に上記大規模ライブラリからスクリーニングして得た候補クローンが、細胞で発現可能か否かを判別することができる工程を備えるスクリーニング方法を提供することを目的とする。 【解決手段】(a)無細胞翻訳系を使用して目的分子のDNAを選択してライブラリを構成し、前記ライブラリに含まれるDNA断片の中から、前記目的分子のDNAを選択し、濃縮して淘汰することによって一次ライブラリを作製する、選択・淘汰工程と;(b)前記選択・淘汰工程で得られた一次ライブラリに含まれる前記目的分子から作られるタンパクのうち、生物において作製可能なタンパクをコードするDNA断片を、細胞を用いて発現させて選択する発現・選択工程と;を備える、目的分子のスクリーニング方法を提供する。

    摘要: An isolated genetically engineered gram-negative bacteria cell having an inwardly leaky outer membrane, wherein the cell has been modified in at least one way, the modification(s) comprising: i) encoding and expressing a pilin domain; ii) knock out or overexpress an outer membrane protein regulator (ompR); iii) activate sigmaE through deletion of Anti-sigma-E factor rseA; iv) overexpress, mutate, or delete baeS and/or baeR; or v) comprise a mutation of cpxA, cpxR, and/or degP, or any combination thereof, wherein said genetically engineered bacteria cell allows large molecules, such as but not limited to intact folded proteins to pass through (or bypass) the outer membrane and enter the periplasmic space.

    摘要: The invention is directed to a conjugate having the general formula (I): Xn – P – YmBo (I), with X is an detection moiety, P is a spacer unit, Y an antigen recognizing moiety, B an oligonucleotide comprising 2 to 300 nucleotide residues and n, m, o are independent integers between 1 and 100 wherein P and B are covalently bound to Y and X is covalently bound to P and wherein X is erasable. Further, the invention is directed to a library of such conjugates and a method of detecting target cells utilizing the conjugates or the library of conjugates.
