Import Complement 3 Assay Kit — Buy in Bulk from Supplier in China

The Complement 3 assay kit from Weifang 3V Bioengineering Group Co., Ltd. is a liquid-phase diagnostic reagent for immunoturbidimetric two-point end assay detection of complement C3 in serum or plasma. It uses latex-enhanced immunoturbidimetry to quantify C3 levels with a measuring range of 0.2 to 2.0 g/L, providing linear results within this span. The kit includes reagents for 100 tests per box, with a shelf life of 12 months when stored at 2 to 8 degrees Celsius away from light.

Formulated as a ready-to-use liquid, the kit minimises manual preparation and reduces pipetting errors. It targets human C3 with antibodies conjugated to latex particles, forming aggregates measured at 340 nm or 570 nm depending on the analyser. Standard calibration uses a five-point curve with human serum-based calibrators, and typical within-run precision is under 5% CV at mid-range concentrations. Controls at low, normal and elevated levels are recommended for quality assurance.

Clinical laboratories use this kit for diagnosing immune complex diseases, monitoring autoimmune disorders and assessing complement activation in sepsis or transplant rejection. Research applications include studying inflammation pathways and validating therapeutic antibodies. The supplier offers FOB and CIF shipping terms, with packaging designed for cold chain transport. Buyers should confirm lead times for bulk orders and verify compatibility with their analyser systems before procurement.

Weifang 3V Bioengineering Group Co., Ltd. is located at No.1198 Zhiyuan Road in the New High-Tech Development District of Weifang, Shandong Province, China.
