1418 results about "Human serum albumin" patented technology

Human serum albumin is the serum albumin found in human blood. It is the most abundant protein in human blood plasma; it constitutes about half of serum protein. It is produced in the liver. It is soluble in water and monomeric.

Improved fibronectin-based binding molecules and uses thereof

The invention provides fibronectin type III (Fn3)-based binding molecules that bind to a specific target antigen. The invention further provides bispecific Fn3-based binding molecules that bind to two or more targets simultaneously. The Fn3-based binding molecules of the invention can also be linked together to form multispecific Fn3-based binding molecules, and / or can be conjugated to a non-Fn3 moiety, such as, Human Serum Albumin (HSA), for improved half life and stability. The invention also provides methods for generating, screening and using Fn3-based binding molecules in a variety of therapeutic and diagnostic applications.

Pharmaceutical proteins, human therapeutics, human serum albumin, insulin, native cholera toxic b submitted on transgenic plastids

Transgenic chloroplast technology could provide a viable solution to the production of Insulin-like Growth Factor I (IGF-I), Human Serum Albumin (HSA), or interferons (IFN) because of hyper-expression capabilities, ability to fold and process eukaryotic proteins with disulfide bridges (thereby eliminating the need for expensive post-purification processing). Tobacco is an ideal choice because of its large biomass, ease of scale-up (million seeds per plant), genetic manipulation and impending need to explore alternate uses for this hazardous crop. Therefore, all three human proteins will be expressed as follows: a) Develop recombinant DNA vectors for enhanced expression via tobacco chloroplast genomes b) generate transgenic plants c) characterize transgenic expression of proteins or fusion proteins using molecular and biochemical methods d) large scale purification of therapeutic proteins from transgenic tobacco and comparison of current purification/processing methods in E. coli or yeast e) Characterization and comparison of therapeutic proteins (yield, purity, functionality) produced in yeast or E. coli with transgenic tobacco f) animal testing and pre-clinical trials for effectiveness of the therapeutic proteins. Mass production of affordable vaccines can be achieved by genetically engineering plants to produce recombinant proteins that are candidate vaccine antigens. The B subunits of Enteroxigenic E. coli (LTB) and cholera toxin of Vibrio cholerae (CTB) are examples of such antigens. When the native LTB gene was expressed via the tobacco nuclear genome, LTB accumulated at levels less than 0.01% of the total soluble leaf protein. Production of effective levels of LTB in plants, required extensive codon modification. Amplification of an unmodified CTB coding sequence in chloroplasts, up to 10,000 copies per cell, resulted in the accumulation of up to 4.1% of total soluble tobacco leaf protein as oligomers (about 410 fold higher expression levels than that of the unmodified LTB gene). PCR and Southern blot analyses confirmed stable integration of the CTB gene into the chloroplast genome. Western blot analysis showed that chloroplast synthesized CTB assembled into oligomers and was antigenically identical to purified native CTB. Also, GM1,-ganglioside binding assays confirmed that chloroplast synthesized CTB binds to the intestinal membrane receptor of cholera toxin, indicating correct folding and disulfide bond formation within the chloroplast. In contrast to stunted nuclear transgenic plants, chloroplast transgenic plants were morphologically indistinguishable from untransformed plants, when CTB was constitutively expressed. The introduced gene was stably inherited in the subsequent generation as confirmed by PCR and Southern blot analyses. Incrased production of an efficient transmucosal carrier molecule and delivery system, like CTB, in transgenic chloroplasts makes plant based oral vaccines and fusion proteins with CTB needing oral administration a much more practical approach.

Human amnion mesenchymal stem cell serum-free culture medium and culture method thereof

ActiveCN101914490ANo other animal originPassivityEmbryonic cellsGerm cellsCartilage cellsOsteoblast
The invention relates to a human amnion mesenchymal stem cell serum-free culture medium and a culture method thereof. The culture medium is formed by adding human serum albumin, human transferrin, human insulin and sodium selenite into a DMEM/F12 basic culture medium. The culture method for the culture medium comprises the following steps of: digesting human amnion by using trypsin, then digesting the human amnion by using collagenase IV and deoxyribonuclease I, and filtering the mixture to obtain single cell suspension; and adding the human serum albumin, the transferrin, the insulin and the sodium selenite into the DMEM/F12 basic culture medium in a ratio of VDMEM to VF12 of 1:1, and putting human amnion mesenchymal stem cells in a 37 DEG C CO2 incubator with saturated humidity and volume fraction of 5 percent under the serum-free condition, wherein culture in vitro and amplification are realized by solution change and transfer of culture, potentiality of multi-direction differentiation is maintained, and the amplified cells can be induced in vitro to form cartilage cells, osteoblasts and adipocytes. The culture medium and the culture method have the characteristics of no other animal sources, wide source and no limitation of ethics.
