Background of CD55/DAF
Complement decay-accelerating factor, also known as CD55 or DAF, is a protein that, in humans, is encoded by the CD55 gene. It is mapped to 1q32.2. This gene encodes a glycoprotein involved in the regulation of the complement cascade. Binding of the encoded protein to complement proteins accelerates their decay, thereby disrupting the cascade and preventing damage to host cells. Antigens present on this protein constitute the Cromer blood group system (CROM). Alternative splicing results in multiple transcript variants. The predominant transcript variant encodes a membrane-bound protein, but alternatively spliced transcripts may produce soluble proteins.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human CD55 PicoKine® Quick ELISA Kit within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

Reproducibility
We ensure reproducibility by testing three samples with differing concentrations of CD55/DAF in ELISA kits from four different production batches/lots.
Reproducibility
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.
