Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of rat C4 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Data

Function Non-enzymatic component of C3 and C5 convertases and thus essential for the propagation of the classical complement pathway. Covalently binds to immunoglobulins and immune complexes and enhances the solubilization of immune aggregates and the clearance of IC through CR1 on erythrocytes (By similarity).
Gene References into Functions
  1. Our study provides the first evidence that sustained selective EPAC activation leads to an increase in TRPC3 and C4 protein expression and induces a proarrhythmic SOCE-like activity in adult rat ventricular cardiomyocytes PMID: 26219954
  2. The expression of the complement component C3f and complement component 4A have potential for use in post-transplant diagnosis of rejection. PMID: 23613499
  3. This study presents the genomic organization of the two C4 gene-containing modules and the expression of the two C4 genes in the rat (Rattus norvegicus). PMID: 15634920
