Background: There are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. There are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. Ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...

A clinical study of lyophilized intravenous human immunoglobulin containing high-titer cytomegalovirus-neutralizing antibody for the treatment cytomegalovirus viremia after allogeneic hematopoietic stem cell transplantation

identification of acid-fast bacilli (afb) in sputum or tissue samples is among definite diagnostic methods of tuberculosis. however, this method of diagnosis is restricted by certain limitations.   serologic diagnosis of tuberculosis (tb) has been used for a long time. the aim of this study was to determine the sensitivity and , specificity of antigen 60 (a60) igg, iga, igm test results in tb d...

The link between IL-13 and bronchial hyper-responsiveness has brought this cytokine as a potential therapeutic target for asthma and allergic diseases. At the present study, we address the role of B cell derived IL-13 in the IgE and other immunoglobulin development. Antisense oligo for human IL-13 m-RNA was used to study IgE down regulation. Human B-lymphocytes were purified by positive selecti...

We have studied somatic cell hybrids between P3x63Ag8 mouse myeloma cells deficient in hypoxanthine phosphoribosyltransferase (EC 2.4.2.8) and either human peripheral lymphocytes or human lymphoblastoid or myeloma cells for the production of human immunoglobulin chains and for the expression of enzyme markers assigned to each of the different human chromosomes. Human chromosome 14 was the only ...

Pregnant cows were successfully hyperimmunized with all four human rotavirus serotypes, resulting in a 100-fold increase in neutralizing milk antibody titers over those of controls. Milk antibodies were isolated batchwise from 1,000 kg of pooled milk for the first 10 lactation days, yielding 10 kg of freeze-dried milk immunoglobulin concentrate consisting of 50% bovine milk immunoglobulins. Mil...
