研究背景 | The protein encoded by this gene is a homeobox-containing transcription factor of the POU domain family. The encoded protein binds the octamer sequence 5'-ATTTGCAT-3', a common transcription factor binding site in immunoglobulin gene promoters. Several transcript variants encoding different isoforms have been found for this gene. |

组织表达 | Isoform 3 is B-cell specific. Isoform 5 is expressed in B-cells and the immunoglobulin-expressing T-cell line MOLT-4, but not in the T-cell line BW5147. |
功能 | Transcription factor that specifically binds to the octamer motif (5'-ATTTGCAT-3'). Regulates transcription in a number of tissues in addition to activating immunoglobulin gene expression. Modulates transcription transactivation by NR3C1, AR and PGR. Isoform 5 activates the U2 small nuclear RNA (snRNA) promoter. |

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) |
