Mouse - Anti-DNA Antibody Assays

High levels of serum autoantibodies against deoxyribonucleic acid (DNA) are observed in most patients with systemic lupus erythematosus (SLE) (1, 2), therefore anti-DNA antibody is considered as a valuable marker for the diagnosis of SLE.  Especially, the serum anti-DNA antibodies form anti-DNA/DNA immune complexes which play important roles in the immunophathogenesis of renal injury known as lupus nephrits (3).  With regards to the specificity of anti-DNA antibodies, anti-single stranded DNA (ssDNA) lgG antibodies are elicited in the early stage of SLE, whereas anti-double stranded DNA (dsDNA) lgG antibody levels correlate with the severity of SLE. On the other hand, anti-dsDNA lgM antibodies are not specific to SLE, but correlate with protection from lupus nephritis in patients with SLE (4, 5). Therefore, evaluation of immunoglobin isotypes against individual DNA types may indicate stages and prognosis of SLE.

Mouse models, which translate relevant information to the human condition, elucidate the cellular and genetic requirements for SLE induction.  For example, in spontaneous murine NZB/W F1 lupus models, anti-dsDNA antibody isotype class switching from lgM to lgG is associates with renal failure which is similar to human SLE (6). Nonetheless, in artificial pristane-induced Balb/c lupus models, anti-ssDNA lgM antibodies solely contribute to SLE induction (7-9). Therefore, to study the diverse contributions of anti-DNA antibodies in these mouse SLE models, Chondrex provides anti-dsDNA lgG (Catalog# 3031) and anti-ssDNA IgG (Catalog# 3041) antibody ELISA kits, as well as anti-dsDNA lgM (Catalog# 3032) and anti-ssDNA lgM antibody ELISA kits (Catalog# 3042).
