BioVector? HEK293T CAGA12-Luc/TK Renilla 是一種專門用于監(jiān)測 Activin 和 TGF-β(轉(zhuǎn)化生長因子-β)信號通路的穩(wěn)定雙熒光素酶報告細(xì)胞系。
物種: 人源(Human)。
組織來源: 胚胎腎臟(Fetal Kidney)。
細(xì)胞類型: 上皮細(xì)胞(貼壁生長)。
生物安全等級: BSL-2。
倍增時間: 約 12–20 小時。
主報告基因 (CAGA12-Luc): 含有 12 個重復(fù)的 CAGA 盒(源自 PAI-1 啟動子),該序列能特異性結(jié)合 Smad3/Smad4 復(fù)合物。當(dāng) TGF-β 或 Activin 激活信號通路時,細(xì)胞會表達(dá)螢火蟲熒光素酶(Firefly Luciferase)。
內(nèi)參報告基因 (TK-Renilla): 由組成型 胸苷激酶 (TK) 啟動子 驅(qū)動,持續(xù)表達(dá)海腎熒光素酶(Renilla Luciferase)。用于校正細(xì)胞數(shù)量、活力及實驗孔間的誤差。
篩選抗性:
Puromycin (嘌呤霉素): 用于維持 CAGA12-Luc 的穩(wěn)定性。
Blasticidin (殺稻瘟菌素): 用于維持 TK-Renilla 的穩(wěn)定性。
培養(yǎng)基: DMEM 高糖培養(yǎng)基,添加 10% 胎牛血清 (FBS/FCS)。
培養(yǎng)環(huán)境: 37°C,5% CO2
生長特性: 貼壁生長;在優(yōu)化條件下倍增時間約為 12–20 小時。
生物安全等級:BSL-2。
檢測原理 (Assay Mechanism)誘導(dǎo): 當(dāng)加入 TGF-β 或 Activin 時,Smad3 和 Smad4 結(jié)合形成復(fù)合物,并結(jié)合到 CAGA12 啟動子區(qū)域。
表達(dá): 結(jié)合后觸發(fā)螢火蟲熒光素酶的表達(dá)。
標(biāo)準(zhǔn)化: 使用雙熒光素酶報告基因檢測系統(tǒng)同時讀取兩種信號。通過螢火蟲熒光素酶與海腎熒光素酶的比值,可以消除細(xì)胞活力、接種誤差以及非特異性藥物反應(yīng)帶來的干擾。

- The BioVector? HEK293T CAGA12-Luc/TK Renilla cell line (Catalog #: 156438) is a specialized reporter cell line designed to monitor Activin and TGF-beta (TGF-β) signaling. It utilizes a dual-reporter system for high-sensitivity measurements and internal normalization.Core Specifications
Host Cell Line:HEK293T (Human Embryonic Kidney), an adherent line known for high transfection efficiency.
Reporter 1 (Inducible):CAGA12-Luc. A Smad3/Smad4-dependent Firefly luciferase reporter containing 12 copies of the CAGA box (AGAC motif) from the PAI-1 promoter. It responds to Activin and TGF-β signaling.
Reporter 2 (Constitutive):TK Renilla. A Renilla luciferase reporter driven by the thymidine kinase (TK) promoter, used as an internal control for normalization.
Selection Markers:Puromycin (conferred by pRetroSuper) and Blasticidin (conferred by pCMV-Bsd).
Application: Monitoring of Smad-dependent signal transduction pathways and screening for TGF-β/Activin pathway agonists or antagonists.
Culture ConditionsGrowth Medium: Dulbecco's Modified Eagle's Medium (DMEM) supplemented with 10% Fetal Calf Serum (FCS).
Storage: 1x10^6 cells/vial, typically stored in liquid nitrogen vapor phase for long-term stability.
Growth Characteristics: Adherent; doubling time is approximately 12–20 hours under optimal conditions.
Biosafety Level:BSL-2.
Assay PerformanceMechanism: In the presence of Activin or TGF-β ligands, Smad3/4 complexes bind to the CAGA12 promoter, triggering the expression of Firefly luciferase.
Normalization: The Renilla luciferase signal provides a baseline for cell viability and transfection efficiency, allowing for "dual-luciferase" normalization.
Sensitivity: Capable of detecting minute moles of reporter protein with a linear range extending over 7 logs.
