The growth hormone supergene family comprises greater than 20 structurally related cytokines and growth factors. A general method is provided for creating site-specific, biologically active conjugates of these proteins. The method involves adding cysteine residues to non-essential regions of the proteins or substituting cysteine residues for non-essential amino acids in the proteins using site-directed mutagenesis and then covalently coupling a cysteine-reactive polymer or other type of cysteine-reactive moiety to the proteins via the added cysteine residue. Disclosed herein are preferred sites for adding cysteine residues or introducing cysteine substitutions into the proteins, and the proteins and protein derivatives produced thereby.

The invention relates to polypeptide conjugates comprising a polypeptide exhibiting G-CSF activity and having an amino acid sequence that differs from the amino acid sequence of human G-CSF in at least one specified introduced and / or removed amino acid residue comprising an attachment group for a non-polypeptide moiety, and having at least one non-polypeptide moiety attached to an attachment group of the polypeptide. The attachment group may e.g. be a lysine, cysteine, aspartic acid or glutamic acid residue or a glycosylation site, and the non-polypeptide moiety may e.g. be a polymer such as polyethylene glycol or an oligosaccharide. The conjugate, which has a reduced in vitro bioactivity compared to hG-CSF, has one or more improved properties such as increased biological half-life and increased stimulation of neutrophils.

Polypeptide conjugates with G-CSF activity comprising a polypeptide having at least one introduced lysine residue and at least one removed lysine residue compared to the sequence of human G-CSF, and which are conjugated to 2-6 polyethylene glycol moieties. The conjugates have a low in vitro bioactivity, a long in vivo half-life, a reduced receptor-mediated clearance, and provide a more rapid stimulation of production of white blood cells and neutrophils than non-conjugated recombinant human G-CSF.

Herein is described a tokenless biometric method for processing electronic transmissions, using at least one user biometric sample, an electronic identicator and an electronic rule module clearinghouse. The steps for processing of the electronic transmissions comprise of a user registration step, wherein a user registers with an electronic identicator at least one registration biometric sample taken directly from the person of the user. A formation of a rule module customized to the user in a rule module clearinghouse, wherein at least one pattern data of a user is associated with at least one execution command of the user. A user identification step, wherein the electronic identicator compares a bid biometric sample taken directly from the person of the user with at least one previously registered biometric sample for producing either a successful or failed identification of the user. In a command execution step, upon successful identification of the user, at least one previously designated rule module of the user is invoked to execute at least one electronic transmission. The above-mentioned steps are conducted in a manner wherein a biometrically authorized electronic transmission is conducted without the user presenting any personalized man-made memory tokens such as smartcards, or magnetic swipe cards.

The present invention relates to methods and compositions for modifying peptides, polypeptides and proteins with polymers, especially glyco-mimetic polymers, so as to improve their biological activity or pharmacokinetic properties. The invention further provides methods and uses for such polymer-modified peptides, polypeptides and proteins. The invention is particularly suitable for use in the synthesis of polymer-modified, synthetic bioactive proteins, and of pharmaceutical compositions that contain such proteins.

The present invention concerns methods and compositions for extending the technique of native chemical ligation to permit the ligation of a wider range of peptides, polypeptides, other polymers and other molecules via an amide bond. The invention further provides methods and uses for such proteins and derivatized proteins. The invention is particularly suitable for use in the synthesis of optionally polymer-modified, synthetic bioactive proteins, and of pharmaceutical compositions that contain such proteins.
