The main objective of this study was to evaluate the effect of dietary inclusion of wheat or corn as the main source of starch in prepartum diets on colostrum composition, colostrum IgG1 and IgG2 concentrations, serum IgG1 and IgG2 concentrations of calves and efficiency of IgG1, IgG2 and total Ig absorption. For this purpose, thirty primiparous and twenty multiparous Holstein cows were used in...

background: the homologous recombination (hr) is one of the conventional cloning methods for the production of recombinant dna. it is a quick method for in vivo dna cloning without using the high cost restriction enzymes. a few modifications in the cloning procedure can increase the efficiency of this method. m aterials and methods: in this study, effect of heating on the rate of the igg1 heavy...

Burosumab (KRN23) is a fully human monoclonal IgG1 antibody that binds excess fibroblast growth factor 23 (FGF23) and has been successfully tested in clinical trials in children with X-linked hypophosphatemic rickets. A report enclosed in this letter gives a brief review of current knowledge on burosumab therapy.

In Leishmania (L.) major-infected BALB/c mice Th2-type cells results in disease progression, whereas C57BL/6-infected mice mount a Th1-type response, which leads to control of the infection. Th2 response correlates with IgG1 whereas, Th1 response supports switching to IgG2a subclasses. Since IgG isotype-dominated response depends on different CD4 + T cell subsets, we studied the antigenic profi...

A/J mice were found to produce autoreactive IgM anti-IgG1 in response to secondary immunization with a number of protein antigens. No anti-IgG1 was produced after a single such immunization, indicating that antigen: IgG1 antibody complexes were responsible for inducing the autoreactive response. The size of the anti-IgG1 response was in some cases massive and of the same order of magnitude as t...
