研究背景 | This gene encodes a major constituent of the human complement subcomponent C1q. C1q associates with C1r and C1s in order to yield the first component of the serum complement system. Deficiency of C1q has been associated with lupus erythematosus and glomerulonephritis. C1q is composed of 18 polypeptide chains: six A-chains, six B-chains, and six C-chains. Each chain contains a collagen-like region located near the N terminus and a C-terminal globular region. The A-, B-, and C-chains are arranged in the order A-C-B on chromosome 1. This gene encodes the B-chain polypeptide of human complement subcomponent C1q |

别名 | C1QB |
功能 | C1q associates with the proenzymes C1r and C1s to yield C1, the first component of the serum complement system. The collagen-like regions of C1q interact with the Ca2+-dependent C1r2C1s2 proenzyme complex, and efficient activation of C1 takes place on interaction of the globular heads of C1q with the Fc regions of IgG or IgM antibody present in immune complexes. |

假设 Input 起始浓度为 a,Ct1 个循环数扩增后达到阈值;IgG 起始浓度为 b,Ct2 个循环数扩增后达到阈值;目的蛋白起始浓度为 c,Ct3 个循环数扩增后达到阈值。则可以得到如下公式:
a×2Ct1 = b×2Ct2 = c×2Ct3 | |
b/a = 2Ct1/2Ct2 = 2(Ct1-Ct2) | b:a=2(Ct1-Ct2) |
c/a = 2Ct1/2Ct3 = 2(Ct1-Ct3) | c:a=2(Ct1-Ct3) |
检测结果=2(Ct1-Ct3)/2(Ct1-Ct2) |
