Rapid and sensitive detection technology is the key to preventing food-borne disease outbreaks. In this study, a low-field nuclear magnetic resonance (NMR) biosensor based on polyamidoamine dendrimers was prepared for rapid of Salmonella in milk. The dendrimer biotinylated by amide reaction chelated diethylene triamine pentacetate acid gadolinium form complexes. antibody complexes were combined...

To examine the intracellular localization of neutral sphingomyelinase 1 (nSMase 1), a rabbit polyclonal antibody was raised against a recombinant form of the enzyme expressed in E. coli. It has been reported that, in rat liver or in ascites hepatoma AH7974, high activity of neutral sphingomyelinase (SMase) is found at the plasma membrane, with a lesser but significant amount in nucleus and cyto...

A convenient assay for monitoring nuclear localization signal-mediated nuclear import of green fluorescent protein (GFP)-variant fusion proteins has been developed. This modified assay relies upon indirect immunofluorescence microscopy for visualization of transported substrates. The use of GFP-variant fusion proteins allows for the rapid assessment of optimal digitonin concentration and permit...

We previously reported that cutaneous vasculitis could be associated with anti-PS/PT antibody and LAMP-2. The copy number of LAMP-2 mRNAs in skin samples from rats induced by intravenous administration after subcutaneous histone injection was significantly higher than without vasculitis. Male Wistar-Kyoto (n=14) were given a dorsal cell-free histones then divided into four groups. Two hours lat...

The expression of nuclear proteins high mobility group (HMG) I and HMGY was investigated in intraepithelial and invasive lesions of the uterine cervix. Human carcinoma cell lines C-41, ME-180, and CaSki were used for testing protein expression in neoplastic cells from the cervix. Morphological grading of the dysplasias (CIN 1, CIN 2, and CIN 3) and invasive carcinomas from formalin-fixed paraff...

introduction: recurrent abortion (ra) may be a consequence of aberrant expression of immunological factors during pregnancy. although the relative importance of immunological factors in human reproduction remains controversial, substantial evidence suggests that autoantibodies contribute to reproductive failure. production of such antibodies is under the control of cytokines; and leptin, beside...
