The invention provides, in part, methods for the production of proteins in a transgenic non-human mammal, wherein the proteins are transported from the blood to the mammary gland for secretion in milk. The transport of the protein to the mammary gland and / or milk is facilitated by binding to a transport receptor in the mammary gland.

The invention discloses a microfluidic protein chip for high-through detecting genetically modified crops. The microfluidic protein chip comprises a nucleic acid chip which is synthesized on the basis of mu ParafloTM microfluidic protein chip and contains six nucleotide sequences and 6 types of antibody-oligonucleotide composite probes, thereby simultaneously detecting 6 transgenetic proteins of trans-bacillus thuringiensis Bt insecticidal crystal protein (Cry1Ac), trans-bacillus thuringiensis Bt insecticidal crystal protein (Cry1c), trans-bacillus thuringiensis Bt insecticidal crystal protein (Cry1F), trans-bacillus thuringiensis Bt insecticidal crystal protein (Cry1Ab), soybean trypsin (SBTI) and neomycin phosphate transferase II gene (NPTII). The invention further provides a transgenic assay kit which comprises a mu ParafloTM microfluidic deoxyribose nucleic acid (DNA) chip which contains six types of probes, six types of antibody-oligonucleotide composite probes, six types of detection antibodies and the like.

This invention is directed to characterizing a host system suitable for the production of functional transgenic proteins, such as anti-human IgG, for use in applications requiring government regulatory approval. It is well known that regulatory agencies required stable, consistent master cell banks and master cell lines for the production of transgenic proteins in order to ensure sufficient material for appropriate characterization, clinical trials, and potential sales. Current plant production systems require the establishment of seed banks for this purpose. However, there are many draw backs related to such a system for the production of a continuous reliable transgenic protein source. An aspect of this invention is directed to characterizing a plant production system suitable for transgenic proteins that meet the stringent regulatory requirements. Another aspect of this invention exemplifies the production and characterization of an anti-human IgG for use as a blood grouping reagents, through the expression of corresponding genes in transgenic alfalfa plants. The cDNAs of the heavy and light chains of a human IgG-specific IgG2a(kappa) murine mAb (C5-1) were transferred into alfalfa through Agrobacterium infection. Transgenic plants expressing the light- and heavy-chain encoding mRNAs were obtained and plants from the Fl progeny (obtained by sexual crossing) were found to express fully assembled C5-1. Furthermore, the transgenic protein was stable in vivo, as well as during extraction and purification procedures. Purification yielded a unique H2L2 form with a reactivity indistinguishable from hybridoma-derived C5-1 in standardized serological tests. Results indicate that plant-derived transgenic proteins, such as mAbs can be used as diagnostic reagents as effectively as hybridoma-derived mAbs, and demonstrates the usefulness of the transformed alfalfa system to produce large amounts of proteins, including multimeric proteins such as mAbs.

The invention discloses a method to produce transgene albumen medicine that takes galactophore expression using adenovirus as carrier. The feature is that: using copying defect type adenovirus framework plamid vector to carry different target albumen gene sequence, and gaining reconstructed albumen carrier from packaging cell in E1A sequence containing Ad5 adenovirus gene group, and gaining instantaneous high expression external target gene medicine albumen. The operation process includes the following steps: separating and cloning target medicine albumen gene sequence; constructing confluence eukaryon expression carrier to testing target albumen to gain external expression right medicine albumen gene; rebuilding the target albumen gene with the adenovirus gene group frame molecule to gain the adenovirus carrier of rebuilt target medicine albumen gene; inducing into animal galactophore; excreting the needed target medicine albumen from latex. The rebuilt albumen could be directly usedto develop kinds of health products and medicine.

The invention relates to a transgenic protein detection method combining antibody modification and terahertz spectrum. The invention aims to provide the method with the characteristics of high accuracy and rapid and convenient detection. According to a technical scheme involved in the invention, the transgenic protein detection method combining antibody modification and terahertz spectrum comprises the steps of: (1) quartz slide cleaning; (2) quartz slide surface modification; (3) quartz slide surface activation; (4) antibody immobilization; (5) quartz slide surface redundant site close; (6) transgenic protein immobilization; (7) acquisition of the terahertz time-domain spectrums of a to-be-measured point on a quartz slide and a reference point; and (8) comparison of the terahertz time-domain spectrums of the to-be-measured point on the quartz slide and the reference point.
