IgY technology offers several advantages over antibody production in mammals. In this study, we applied IgY technology for the production of anti-mouse IgG polyclonal antibodies and developed a FITC conjugate reagent. Two hens were immunized 3 times with mouse IgG, one via the pectoralis and the other via the calf muscles. Specific antibodies could be(More)
The leukocyte surface molecule CD99 is an integral membrane glycoprotein encoded by the E2/MIC2 gene. This molecule is broadly expressed on cells of the hematopoietic system and displays two surface forms, a long 32 kDa form and a short 28 kDa form. While the complete function of the CD99 molecule is unclear, it has been reported to be involved in(More)
In order to identify new molecules involved in regulation of T cell proliferation, we generated various mAb by immunization of mice with the T cell line Molt4. We found one mAb (termed P-3E10) that down-regulated the in vitro T cell proliferation induced by CD3-specific OKT3 mAb. The P-3E10 mAb was also able to inhibit IFN-gamma, IL-2, IL-4 and IL-10(More)
CD147 is a leukocyte surface molecule which belongs to the immunoglobulin superfamily. It is broadly expressed on various cell types and is a lymphocyte activation-associated molecule. In order to study the function of CD147, five CD147 monoclonal antibodies (mAbs) were generated: M6-2F9; M6-1D4; M6-1F3; M6-1B9; and M6-1E9. Biochemical characterizations and(More)
Antimutagenicity and chemopreventive activity of an 80%-ethanol extract of bitter melon (Momordica charantia Linn.) against the formation of azoxymethane (AOM)-induced aberrant crypt foci (ACF) was investigated. The bitter melon extract was nonmutagenic and inhibited the mutagenicity of heterocyclic amines 2-amino-3,4-dimethylimidazo[4,5-f]quinoline and(More)
Multidrug resistance (MDR) in leukemia is commonly associated with the expression of a transmembrane protein, P-glycoprotein (P-gp). In this study, two monoclonal antibodies (mAbs) specific for the extracellular domain of P-gp were generated. By employing the generated mAbs, a two-color lysed whole blood flow cytometric method for surface P-gp and an(More)
Alpha-thalassaemia 1 genetic disorder occurs when there is a deletion of two linked alpha-globin genes. The interaction between these abnormal genes leads to the most severe type of thalassaemia disease, haemoglobin (Hb) Bart's hydrops fetalis. The identification of alpha-thalassaemia 1 carriers and genetic counselling are essential for the prevention and(More)
Monoclonal antibodies against α-globin containing human Hbs, named AMS-Alpha1 and AMS-Alpha 2, were produced by the hybridoma technique using spleen cells enriched by the newly developed B lymphocyte enrichment protocol. These two monoclonal antibodies were of IgM class, reacting to only intact form of human Hbs A, A2, E, and F, which contain α-globin(More)
The expression of LFA-1 diverges from the physiological condition, thus active targeting carrier can provide the benefits from difference into LFA-1 expression in various conditions. Here, the selectivity of cIBR-conjugated nanoparticles (cIBR-NPs), in terms of uptake, was investigated using PBMCs, Mixed PBMCMolt-3 cells and Molt-3 cells. The expressions of(More)
Beta3 subunit is described as one of the Na, K ATPase subunits. Recently, we generated a monoclonal antibody (mAb), termed P-3E10. This mAb was shown to react with the Na, K ATPase beta3 subunit or CD298. By immunofluorescence analysis using mAb P-3E10, it was found that all peripheral blood leukocytes express Na, K ATPase beta3. The presence of beta3(More)
