Chicken egg yolk antibodies (IgY) against camel immunoglobulins were generated and their specificity was shown by double immunodiffusion, immunoelectrophoresis, and Western blotting. Anti camel antibodies specifically react to camel antibodies in immunodiffusion and immunoelectrophoresis were demonstrated. Western blotting revealed that IgY antibodies recognize the heavy chain in a number of ma...

since 20th  century, when allergy was defined, an ongoing attempt for discovering the mechanisms underlying it and its treatment began. defining allergens as well as cells such as regulatory t-cells and characterizing the antibodies involved in the pathogenesis (including blocking antibodies) have helped very much towards a better understanding of the immunologic process.however, allergen speci...

background: pemphigus is an autoimmune bullous disease and it is unclear what triggers and deteriorates it. the current study aimed to evaluate whether increasing the igg antibody titer represents a good indicator of the pemphigus recurrence. objectives: the current study aimed to evaluate whether increasing igg titer is an indicator of the expected recurrence. patients and methods: the current...

using complement fixation technique, serial serum samples from 15 patients undergoing surgical removal of malignant tumors were assayed for the presence of tumors antibodies against the cellular fractions of both normal and carcinomatous tissue. antibody responses against tumor associated antigens were detected in four cases. in all cases antibody activity was directed only against the supernat...

we have employed a peptide-based antibody generation protocol for producing antibody against human nestin. using a 12-mer synthetic peptide from repetitive region of human nestin protein devoid of any n- or o-glyco-sylation sequences, we generated a mouse monoclonal antibody capable of recognizing human, mouse, bovine, and rat nestin. a wide variety of nestin proteins ranging from 140-250 kda w...

background and aims: human parvovirus b19, a member of the parvoviridae family, with single-stranded dna is a very minute non-enveloped virus. b 19 virus is mostly transmitted via the respiratory tract but some studies have been reported which b19 virus can be transmitted through blood and/or blood products. the aim of this study was to evaluate the prevalence of b19 among blood donors in tehra...

conclusions the hav seroprevalence of 90.8% in the studied region may be representative of a highly endemic region of hav that does not require a vaccination program to be commissioned. results it was found that 455 out of 501 (90.8%) serum samples, including those of 211 (42.1%) men and 290 (57.9%) women, were positive for hav igg antibody. education level, age, marital status, and ethnicity w...

conclusions our results demonstrated that r-fla-a could induce cellular and humoral immune response as proper stimulant of poly-isotypic humoral responses. results immunized mice with adjuvanted flagellin showed a considerably increased lymphocyte proliferation compared with the control group (p = 0.004). high level of il-4 and ifn-γ secretion was observed in immunized mice compared with the co...
