Abstract:
Abstract Antibodies have the ability to bind various types of antigens and to recognize different antibody-binding sites (epitopes) of the same antigen with different binding affinities. Due to the conserved structural framework of antibodies, their specificity to antigens is mainly determined by their antigen-binding site (paratope). Therefore, characterization of epitopes in combination with describing the involved conformational changes of the paratope upon binding is crucial in understanding and predicting antibody-antigen binding.

Abstract Current approaches for generating major histocompatibility complex (MHC) Class-I proteins with desired bound peptides (pMHC-I) for research, diagnostic and therapeutic applications are limited by the inherent instability of empty MHC-I molecules. Using the properties of the chaperone TAP-binding protein related (TAPBPR), we have developed a robust method to produce soluble, peptide-receptive MHC-I molecules in Chinese Hamster Ovary cells at high yield, completely bypassing the requirement for laborious refolding from inclusion bodies expressed in E.coli.

Abstract:
Until now, psoriatic antigen as a specific antigen derived from some infectious agent potentially related to origin of psoriasis has not been identified, thereby strongly arguing against infectious theory of psoriasis. However, the lack of specific psoriasis-associated antigens may be theoretically accounted for by an idea that psoriatic antigen could be analogous to infectious prion proteins (PrPSc analogue). It might be identical to some epidermal protein in psoriasis-free subjects that might differ antigenically from related normal protein by resistance to digestive enzymes similarly to PrP

Abstract Bacterial flagellin is a potent adjuvant that enhances adaptive immune responses to a variety of antigens. The vaccinia virus antigens L1R and B5R are highly immunogenic in the context of the parent virus, but recombinant forms of the proteins are only weakly immunogenic. Therefore, we evaluated the response to these antigens when flagellin was used as an adjuvant. We found that flagellin promoted a robust antigen-specific humoral response to poxvirus antigens delivered intranasally and intramuscularly, but intramuscular immunization was more efficient.

The LC genes are encoded by two separate loci, subdividing the entity of antibodies into kappa (LCκ) and lambda (LCλ) isotypes that exhibit distinct sequence and conformational preferences.

Some of the tick protective antigens are serpins, a promising target for animal immunization and infection control.

Abstract:
Protein S circulates in plasma as free protein S and in complex with C4b-binding protein, an inhibitor of complement activation. Only free protein S functions as the cofactor for the anticoagulant and profibrinolytic effects of activated protein C. Since isolated reductions of protein C and protein S result in increased thrombotic risk, only measurement of both proteins permits comprehensive evaluation of the antithrombotic potential of the protein C system. No information is available on protein C and protein S functional levels during the postoperative period, an established prothrombotic co

The laboratory diagnosis of congenital deficiency of these proteins represents a major problem since a large proportion of patients are on oral anticoagulation (OA) at the time the deficiencies are suspected.Under these circumstances the availability of a reference interval obtained in patients on stabilized OA has proven useful.Functional (C) and antigenic

Abstract:
Activated protein C functions as an anticoagulant by enzymatically degrading factors Va and Villa in the clotting cascade. Protein C may be converted to its enzymatically active form bythrombin. The rate at which thrombin cleavage of the zymogen occurs is greatly enhanced when thrombin is bound to an endothelial cell receptor protein, thrombomodulin. Activated proteinC has a relatively long half-life in vivo and the formation of activated protein C in response to low level thrombin infusion suggests that the protein C system may provide a feedback mechanism to limit blood clotting.

Abstract:
Micro and nano Au/Cr and Al thin film devices have been fabricated using DC sputtering and e-beam evaporation in combination with e-beam and photo lithography. These devices can be coated with specific reagents to detect and measure the presence of particular antigens and/or complementary DNA sequences with a smaller sample size and at much earlier stages of disease progression compared to current medical diagnostic technologies. Using the device material stack (Au/Cr/Si), we have assessed the binding affinity of Au, Cr, and Si with Protein G, and antibodies for Prostate Specific Antigen (PSA)

Abstract:
Betanodaviruses are causative agents of viral nervous necrosis (VNN), a devastating disease of cultured marine fish worldwide. Betanodavirus (BTN) genome is composed of two single-stranded, positive-sense RNA molecules. The larger genomic segment, RNA1 (3.1 kb), encodes the RNA-dependent RNA polymerase, while the smaller genomic segment, RNA 2 (1.4kb), encodes the coat protein. This structural protein is the host-protective antigen of VNN which assembles to form virus-like particles (VLPs). BTNs are classified into four genotypes, designated red-spotted grouper nervous necrosis virus (RGNNV),

Abstract:
During the development of this project, we selected four potential B. bovis antigens for a subunit vaccine to prevent the clinical signs of acute bovine babesiosis. Selection of the target antigens was based on: (1) profile of expression in parasite blood stages; (2) prediction for protein location on the parasite surface and/or on the surface of infected red blood cells; and (3) target conservation between US and Israeli strains of B. bovis. Following these criteria, the B. bovis targets BBOV_IV009170, BBOV_III007410, BBOV_II001790, and BBOV_III008720 were selected. Full-length genomic sequen
