Description
ã€Intended use】
The C4 is a quantitative turbidimetric test for the measurement of
C4 in human serum or plasma.Â
ã€Principle of the method】
Anti-human C4 antibodies when mixed with samples containing C4,
form insoluble complexes. These complexes cause an absorbance
change, dependent upon the C4 concentration of the patient sample,
that can be quantified by comparison from a calibrator of know C4
concentration.
ã€Reagent composition 】
Diluent（R1） ：PBS buffer *0 mmol/L, PEG ***0, Surfactant.
Antibody（R2）：PBS buffer *0 mmol/L, Goat serum, anti-human C3,
Preservative.
ã€Storage and Shelf Life】
1.Sored tightly closed at **8ºC .
2.Non-open kit stored tightly closed at **8ºC has *2 month
shelf life, once opening, the kit has one more month at
**8ºC storage。
ã€Applied analyzer】
Spectrophotometer or biochemical analyzer with **0nm
wavelength.
ã€Sample】
Fresh serum or plasma. Do not use highly hemolized or lipemic
samples. If not determine in time, store at **0 ℃. Avoid repeat
freezing and melting.
ã€Procedure】
1. Assay method：two point，wavelength **0nm
2.  Application on chemistry analyzer:
