Reference Typing Report for Complement Component C4

Experimental and Clinical Immunogenetics, 1998
During the 7th Complement Genetics Workshop, Mainz, Germany, May 1998, a complement component C4 typing exercise took place with the aim of applying present technologies to the definition of <i>reference C4 alleles/phenotypes</i> and the recognition of nonexpressed (Q0) C4 alleles within expressed haplotypes.

Complement components (C3, C4) in childhood asthma

The Indian Journal of Pediatrics, 2005
To assess the involvement of complements (C3, C4) in the pathophysiology of bronchial asthma.Selection of patients (n = 64) were made according to the recommended international criteria for diagnosis and classification of asthma. Serum levels of complement components (C3, C4) were measured by radial immunodiffusion technique in 64 Libyan children (age:

Interaction of nucleophilic compounds with complement component C4

Comparative Immunology, Microbiology and Infectious Diseases, 1988
Drugs which induce systemic lupus erythematosus as a toxic side effect have been shown to inhibit the covalent binding of C4, which is an important event in immune complex clearance in normal individuals. Human C4 is encoded at two polymorphic loci, C4A and C4B within the Major Histocompatibility Complex and patients with idiopathic SLE are more likely

Isolation of the Fourth Component (C4) of Rat Complement

The Journal of Immunology, 1979
Abstract The fourth component of rat complement was purified to homogeneity by sequential chromatography of rat plasma in benzamidine on QAE-A50, SP-C50, hydroxyapatite, and gel filtration on Bio-Gel A 1.5. The final material was homogeneous on SDS-PAGE analysis and had a calculated m.w. of 198,000. A monospecific antibody against rat C4

The complement component C4 in sudden infant death

European Journal of Pediatrics, 1999
The aim of the present study was to compare partial deletions of the complement C4 gene in victims of totally unexplained sudden infant death (SID) (n = 89) and borderline SID (n = 15) with and without slight infections prior to death, in cases of infectious death (n = 19), and in living infants with and without infections (n = 84).

Family studies of complement C4 and HLA in man

Human Genetics, 1981
At least 12 different C4 gene products with a three band pattern have been identified after electrophoresis of sera pretreated with neuraminidase. Segregation analysis showed at least 12 different C4 haplotypes (or supergenes), of which five represent a single gene product and seven are duplications each composed of an F and an S gene.

Post-transcriptional regulation of complement C4 in low C4-producing strain of mouse

Immunogenetics, 1990
The expression of the fourth component of complement (C4) of the mouse can differ 20-fold and is determined by C4-high (C4h) or C4-low (C4l) alleles. To investigate the molecular mechanisms underlying the differences in C4 expression, we compared the transcriptional activity of the C4 genes between high and low C4-producer strains of mice (B10 and FM ...

Detection of complement C4 with a piezoelectric immunosensor

Chinese Journal of Chemistry, 1998
AbstractA piezoelectric immunosensor has been developed for the detection of complement C4. Anti‐C4 antibody was immobilized onto the gold electrodes of a 9 MHz AT‐cut piezoelectric crystal. The coated crystal with the physical adsorption method to immobilize antibody showed the better results than the polyethyleneimine adhesion, glutaraldehyde cross ...

Complement C4 allotype association with and serum C4 concentration in an autoimmune disease in the dog

Clinical Immunology and Immunopathology, 1985
Serum C4 concentrations and C4 allotypes were determined wherever possible on eight dogs with an autoimmune disorder characterized by antinuclear antibody (ANA) positivity, pyrexia, and seronegative arthritis. Three of the six dogs tested serially showed hypocomplementemia at disease onset with return to normal concentrations with clinical remission ...
