    • The invention features the use of a peptide for transferring genes in a eukaryotic target cell, which peptide has about 10 to about 200, in particular about 15 to about 150 amino acids, and advantageously about 20 amino acids, in which 30 % at least of the amino acids are constituted by proline radicals, which proline radicals are regularly arranged so as to induce polypeptide chain turnings at about 180 DEG (" beta -turn" or "reverse-turn"), these turns being regularly spaced and gathering in a polyproline beta -turn helix, in a polypeptide construction containing, on the said peptide N-terminal side (upstream), an N-terminal (upstream) proteinic domain capable of recognising a targeted surface molecule or an antigen expressed on a cellular surface, in particular an appropriate receptor (targeted receptor) located on the said eukaryotic cell, and on the said peptide C-terminal side (downstream), a C-terminal (downstream) protein domain capable of recognising an appropriate receptor (auxiliary receptor) located on the said eukaryotic cell, which peptide is capable of facilitating or inhibiting interaction between the C-terminal (downstream) protein domain and the auxiliary receptor, the inhibition of this interaction taking place so long as the N-terminal (upstream) protein domain has not interacted with the targeted receptor, and the facilitating of the interaction between the C-terminal (downstream) protein domain and the auxiliary receptor taking place when the N-terminal (upstream) protein domain has interacted with the targeted receptor.

    • The invention concerns an optical component of polarizing modulation, a polarimeter and a Mueller ellipsometer comprising this optical component. The optical component modulates an incident light beam (10) linearly polarized and sends back a modulated beam (11). It comprises a coupled phase modulator (6B) modulating twice successively the incident beam, the two modulations being at the same frequency omega /2 pi and being coupled by a system (61) modifying the state of polarization of the light between the two modulations. The ellipsometer comprises means for sensing a measuring beam sent back by a sample, which receives the modulated beam, and a processing unit. The sensing means include a polarimeter generating n measured quantities representing the states of polarization of the beam and the processing unit generates by Fourier transform m values for each of these quantities, with n x m >/= 16 and m >/= 4, for simultaneously acceding to the sixteen coefficients of the Mueller matrix of the sample.
