According to the method of the present invention, a protein and hydrophilic polymer are contacted in the presence of at least one organic solvent and at least one metal chelator, under conditions that promote the formation of a conjugate of the protein and polymer. Thus, the invention is directed to the site-specific modification of selected proteins, such as insulin, with poly(ethylene glycol) at residue PheB1. The invention also provides a pharmaceutical formulation for encapsulating the conjugate in a biodegradable polymer. Full Article
ria Monoclonal thyroid stimulating or blocking antibodies, peptide sequences corresponding to their variable regions, and their uses in diagnostic, preventive and therapeutic medicine By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT Monoclonal antibodies (mAbs) having thyroid stimulating activity (TSAb), especially full or considerably agonistic activity, or thyroid blocking activity (TBAb), which are obtainable by genetic immunization of mice, or fragments (F(ab')2, Fab or Fv) or humanized forms of such monoclonal antibodies or single chain forms (SCA; scFv) of such fragments, which antibodies, or their fragments, compete with bovine TSH for epitopes of the human TSHr, compete with autoantibodies from sera from Graves' patients as well as with autoantibodies from sera from patients harboring blocking autoantibodies for epitopes of the human TSHr, bind to conformational epitopes of the human TSHr located in the first 281 amino acids of the human TSHr, and usually also bind to TSFR receptors (TSHr) from different animals. Various uses of such antibodies, or of peptides corresponding to variable regions of such antibodies, are also described and claimed. Full Article
ria Resonance circuit with variable diodes By www.freepatentsonline.com Published On :: Tue, 24 Mar 2009 08:00:00 EDT A resistance having a high impedance is connected between anode terminals of two variable capacitance diodes sharing a cathode, and the components described above are sealed in one package. The resistance can be formed of a diffusion region between p-regions of the variable capacitance diodes or can be formed of polysilicon and disposed on a chip. Thus, the resistance can be mounted while a chip size of the variable capacitance diode is maintained. Accordingly, it is not required that a bias resistance having a high impedance is additionally provided, whereby achieving reduction in the substrate mounting area and reduction in costs of the set.

ria Variable tuning circuit using variable capacitance diode and television tuner By www.freepatentsonline.com Published On :: Tue, 27 Oct 2009 08:00:00 EDT The invention provides a variable tuning circuit capable of extending a variable range in a high frequency band, ensuring the value of L of an inductor to increase the value of Q of a circuit in a low frequency band, and preventing a reduction in gain, an increase in noise, and unstable oscillation. A variable tuning circuit includes: a first parallel resonance circuit that includes a varactor diode, a capacitor connected in series to the varactor diode, and a first inductor connected in parallel to the varactor diode and the capacitor; and a second parallel resonance circuit that includes a second inductor connected in parallel to the varactor diode with a direct current cut-off capacitor interposed therebetween. When the varactor diode has a maximum capacitance, a resonant frequency of the second parallel resonance circuit is set about a lowest frequency in a variable frequency range. Full Article
ria Apparatus, system and methods for enabling linearity improvement in voltage controlled variable capacitors By www.freepatentsonline.com Published On :: Tue, 17 Aug 2010 08:00:00 EDT An embodiment of the present invention provides an apparatus, comprising at least one anti-parallel pair VVC network comprised of two parallel VVCs with one biased in the opposite polarity of the other and at least one anti-series VVC network comprised of two VVCs configured in series, one biased in the opposite polarity of the other such that the resulting AC capacitive variations produce a desired capacitance variation.
