Ig heavy chain variable region gene complex of lupus mice exhibits normal restriction fragment length polymorphism
B cell hyperactivity, hypergammaglobulinemia, and autoantibody expression, the hallmarks of systemic lupus erythematosus, might be associated with structural abnormalities within the Ig heavy chain variable region (Igh-V) gene complex. The Igh-V loci from several lupus-prone mouse strains, their ancestors, and other nonautoimmune mice were therefore analyzed by restriction fragment length polym...
متن کاملRestriction Fragment Length Polymorphism (RFLP)
Restriction Fragment Length Polymorphism (RFLP) is a technique in which organisms may be differentiated by analysis of patterns derived from cleavage of their DNA. If two organisms differ in the distance between sites of cleavage of a particular restriction endonuclease, the length of the fragments produced will differ when the DNA is digested with a restriction enzyme. The similarity of the pa...
متن کاملAnalysis of restriction fragment length polymorphism in lymphokine genes of normal and autoimmune mice
Analysis of RFLP has been employed in lymphokine genes of autoimmune and normal mice. No polymorphism could be detected in the loci containing IL-2, IL-2 receptor, IL-5, and IFN-gamma in NZB, NZW, BxSB, and MRL/lpr mice when compared with normal mice. Allelic forms were identified in the IL-1 alpha gene of BALB/c and in the IL-4 gene of NZW. The frequency of the Bam HI RFLP in the TNF-alpha gen...
متن کاملDifferential usage of an Ig heavy chain variable region gene by human B-cell tumors.
A monoclonal anti-idiotypic antibody has been raised that recognizes Igs with heavy chains encoded by a member of the VH4 family, the VH4-21 gene segment. The idiotope (Id) is detectable on a high percentage of early B cells in fetal spleen, and is expressed by certain autoantibodies, particularly cold-reactive anti-red blood cell antibodies. Therefore, it was of interest to investigate usage o...
متن کاملDetection and differentiation of old world orthopoxviruses: restriction fragment length polymorphism of the crmB gene region.
A restriction fragment length polymorphism (RFLP) assay was developed to identify and differentiate Old World, African-Eurasian orthopoxviruses (OPV): variola, vaccinia, cowpox, monkeypox, camelpox, ectromelia, and taterapox viruses. The test uses amplicons produced from virus genome DNA by PCR with a consensus primer pair designed from sequences determined for the cytokine response modifier B ...
