摘要:
Methods for producing proteins and glycoproteins in Pichia pastoris that lack detectable cross binding activity to antibodies made against host cell antigens are described. In particular, methods are described wherein recombinant Pichia pastoris strains that do not display a β-mannosyltransferase 2 activity with respect to an N-glycan or O-glycan and do not display at least one activity selected from a β-mannosyltransferase 1, 3, and 4 activity to produce recombinant proteins and glycoproteins. These recombinant Pichia pastoris strains can produce proteins and glycoproteins that lack detectable α-mannosidase resistant β-mannose residues thereon and thus, lack cross binding activity to antibodies against host cell antigens. Further described are methods for producing bi-sialylated human erythropoietin in Pichia pastoris that lack detectable cross binding activity to antibodies against host cell antigens.

摘要:
The present invention relates to novel variants of domain 2 of the human placental bikunin with improved expression levels and favorable serine protease-inhibitory properties and their production and use.
摘要:
A modified amyloid precursor protein can be expressed from a DNA construct comprising an APP DNA sequence, or a fragment or artificial substrate thereof, encoding the mutation I45W, I45Y, V46W or V46Y (numbering relative to A4CT); the use of the DNA construct in the generation of cell lines or transgenic animals and the use of these proteins or such transgenic animals in the diagnosis of Alzheimer's Disease and screening putative drugs against Alzheimer's Disease are also described.
摘要:
The present invention relates to complexes and fusion proteins comprising a CD91 ligand and an antigenic molecule, for use in the treatment or prevention of a disease. The invention specifically provides complexes comprising a CD91 ligand noncovalently bound to, or alternatively crosslinked to, an antigenic molecule. The invention also specifically provides fusion proteins comprising a CD91 ligand fused via a peptide bond to an antigenic molecule.
摘要:
The instant invention involves the use of a combination of preparatory steps in conjunction with mass spectroscopy and time-of-flight detection procedures to maximize the diversity of biopolymers which are verifiable within a particular sample. The cohort of biopolymers verified within such a sample is then viewed with reference to their ability to evidence at least one particular disease state; thereby enabling a diagnostician to gain the ability to characterize either the presence or absence of said at least one disease state relative to recognition of the presence and/or the absence of said biopolymer, predict disease risk assessment, and develop therapeutic avenues against said disease.
摘要:
A non-human transgenic mammalian animal, as described above, contains one or more exogenous double stranded DNA sequence(s) stably integrated into the genome of the animal, which comprises trans-acting regulatory units controlling expression of DNA sequences encoding proteins to be secreted into the milk of transgenic mammals. The DNA sequence of the trans-regulatory gene encodes transcriptional activating proteins, which are not secreted but made in a temporally controlled and mammary tissue specific manner. The DNA sequence containing the protein to be secreted in the milk is constructed on a separate gene sequence under the regulation of a minimal promoter and a trans-activation binding domain. The transgenic mammals are preferably pigs, cows, sheep, goats and rabbits. A related composition and method for making transgenic proteins which require specialized propeptides for proper post-translational processing is also described.
摘要:
The invention relates to a method for producing a bikunin plasma fraction having antitrypsin activity. A source containing the bikunin plasma fraction is separated into components by means of molecular exclusion chromatography and a fraction having antitrypsin activity is collected.
