線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of human C7 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:100	Average %	91
	Range %	87-95
1:200	Average %	95
	Range %	90-100
1:400	Average %	97
	Range %	94-101
1:800	Average %	94
	Range %	91-98

回收率：

The recovery of human C7 spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	90	87-94
EDTA plasma (n=4)	99	93-105

Functional genetic variants in complement component 7 confer susceptibility to gastric cancer S Wang,PeerJ,2022

功能：

Constituent of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells. C7 serves as a membrane anchor.

1. this study shows that GG genotype of C7 provides protection against fibrosis severity while showing a higher risk for hepatocellular carcinoma in patients with hepatitis C PMID: 29966690
2. Two case reports of C7 deficiency leading to recurrent meningitis and other bacterial infections are described. PMID: 28078901
3. The complement C7 rs6876739 CC genotypes and mannan-binding lectin (MBL2) gene polymorphisms of liver donors were significantly associated with bacterial infection in recipients. PMID: 27063552
4. Complement proteins C7 and CFH control the stemness of liver cancer cells via LSF-1 pathway. PMID: 26723877
5. Borrelial CspA binds the human terminal complement components C7 and C9 and blocks assembly and membrane insertion of the terminal complement complex (TCC). PMID: 23943762
6. Studies indicate that the deletion defect may be a more commonly distributed cause of C7 deficiency in Ireland. PMID: 22206826
7. C7 isoelectric focusing variants can determine meningococcal killing in the early stage of infection when antibody-independent killing prevails. PMID: 19931914
8. To determine transcriptional regulation of the human complement component C7, a 1 kb promoter fragment was cloned and the transcription start site was determined. C7 is expressed by the hepatoma-derived cell line Hep-3B, but not by Hep-G2. PMID: 12595902
9. The interaction between the factor I domain of C7 and the C345C domain at the C terminus of the C5 alpha-chain plays an essential role in complement membrane attack complex formation and complement lytic activity. PMID: 15879120
10. recurrence of fulminant meningococcal disease in a complement component C7-deficient patient PMID: 15889368
11. membrane associated C7 acts as a trap for the late complement components to control excessive inflammation induced by SC5b-9 PMID: 19179470
12. C7 is associated with multiple sclerosis pathogenesis. PMID: 19221116
13. Data show that the two C7-FIMs pack closely together with an approximate 2-fold rotational symmetry that is rarely seen in module pairs and has not been observed in FD-containing proteins. PMID: 19419965
