Polyclonal anti-T cell antibodies or antilymphocyte serum (ALS) are xenogeneic antihuman polyclonal antibodies, more precisely antithymocyte globulins (ATG). They are prepared by immunizing rabbits or horses with human lymphoid cells derived from the thymus. They were first prepared for clinical use in horses [1] and followed by a more potent preparation in rabbits. Despite some problems of usi...

Background: SLC39A6 Protein (solute carrier family 39) or LIV-1 is a zinc transporter protein that is overexpressed in positive estrogen cancers such as breast cancer. The LIV-1 protein transfer zinc into the cytoplasm through the plasma membrane. Today it is known that just as a decrease in the concentration of zinc in the cell can cause cancer, an excessive increase in the concentration of zi...

Endotoxin protein (EP) has been shown to be a mitogen and polyclonal activator of human peripheral blood lymphocytes. EP stimulates proliferation of B lymphoyctes in the absence of T cells, and this activation is nonspecific by a number of parameters. Additionally, EP mitogenesis, but not polyclonal activation, is inhibited in the presence of human serum, suggesting that these events are dissoc...

background: during the last twenty years, the extraction of specific egg yolk (igy) antibodies from the immunized chickens has been accepted as a useful alternative to the immunization of mammals. the aim of the present study was immunizing the chickens with human umbilical cord serum (hucs) and the extraction of specific anti-human globulins (igg, c3b, and c3d) antibodies from egg yolk in orde...

Mass transfer in a protein A medium with silica matrix was analyzed this study. Using confocal laser scanning microscopy, we monitored the positional and temporal changes polyclonal human IgG during batch adsorption. simple theoretical model based on Fick’s law of diffusion Langmuir adsorption used to numerically approximate external intraparticle mass-transfer properties single particles. The ...

INTRODUCTION This case report demonstrates that the differential immunohistochemical reactivities of Siemens' Double Antibody Glucagon compared to DakoCytomation's Polyclonal Rabbit Anti-Human Glucagon allow for pathologic distinction of enteral versus pancreatic glucagonoma. CASE PRESENTATION A 64-year-old Caucasian man was diagnosed with a duodenal enteroglucagonoma following presentation w...

Antibodies are essential tools of biomedical and biochemical researches. Polyclonal antibodies are produced against different epitopes of antigens. Purified F(ab')2 can be used for animal's immunization to produce polyclonal antibodies. Human immunoglobulin G (IgG) was purified by ion exchange chromatography method. In all stages verification method of the purified antibodies was sodium dodecyl...

Transient receptor potential vanilloid type 1 (TRPV1) can be activated by multiple chemical and physical stimuli such as capsaicin, anandamide, protons, and heat. Capsaicin interacts with the binding pocket constituted by transmembrane regions 3 and 4, whereas protons act through residues in the prepore loop of TRPV1. Here, we report on characterization of polyclonal and monoclonal antibodies t...

Venomous snakebite is a life-threatening injury in many tropical and subtropical areas including Iran. The gold standard treatment option for human envenomation is the use of antivenoms. Despite the unique effects of horse-derived antivenoms on the treatment of snakebite, they are not fully perfect and need improvements. In this study, human recombinant Fab fragment antivenom was produced in Ro...

Monoclonal antibodies to purified human urinary kallikrein have been developed. Selection of antibody producing clones was based on 125I-kallikrein binding activity of hybridoma media in both radioimmunoassay and enzyme-linked immunosorbent assay. Three clones (2 IgG1, 1 IgG2b) were subcloned, characterized, and compared with the polyclonal antiserum generated in rabbits immunized with the puri...
