BioVector? TB096(通常指 TB096-2)是一種源自患者的具有 IDH1 突變的人類星形細胞瘤(Astrocytoma)細胞系。它是研究膠質瘤中 IDH1 功能增益突變及其致癌代謝物 D-2-羥基戊二酸 (D-2HG) 的重要體外模型。

生物學與遺傳學特征
  • 來源: 衍生自一名 26 歲男性的間變性星形細胞瘤(Anaplastic Astrocytoma)樣本。

  • 關鍵基因突變:

    • IDH1: 雜合突變 Arg132His (p.R132H)。

    • TP53: 純合突變 Gly245Val (p.G245V)。

    • ATRX: 無義突變 Arg781Ter。


  • 代謝特征: 該細胞系能夠持續(xù)產生高水平的 D-2-羥基戊二酸 (D-2HG),這是研究膠質瘤發(fā)病機制的關鍵生物標志物。

培養(yǎng)與維護指南
根據 BioVector? NTCC Inc,技術說明書 (Datasheet) 的建議,主要操作規(guī)程如下:
  • 生長特性: 貼壁生長。

  • 推薦培養(yǎng)基: 建議使用專用的 BioVector?TB096-2 Expansion Medium(TB096-2 擴增培養(yǎng)基)以維持其遺傳表型。

  • 傳代操作:

    • 消化: 建議使用 Accutase?(在 37°C 下孵育 3–5 分鐘)進行細胞解離,避免使用強力胰酶以保持細胞活力。

    • 傳代比例: 細胞匯合度達到約 80% 時進行傳代,建議比例為 1:6


  • 凍存: 長期儲存在液氮中(–196°C)。凍存液配方通常為:TB096 擴增培養(yǎng)基 + 10% DMSO。

  • 穩(wěn)定性: 經證實,在解凍后至少 10 代內可保持穩(wěn)定的標記物表達和功能。

主要應用領域

  • 藥物篩選: 篩選針對 IDH1 突變酶的小分子抑制劑。

  • 代謝研究: 研究 IDH1 突變如何改變細胞代謝組學并驅動腫瘤進展。

  • 表觀遺傳學: 探索 D-2HG 誘導的 DNA 高甲基化對星形細胞瘤發(fā)展的影響。


The TB096 (also known as TB096-2) is a patient-derived human cell line used primarily to study IDH1-mutated astrocytoma. It is characterized by its ability to model the gain-of-function IDH1 mutation, which converts alpha-ketoglutarate into the oncometabolite D-2-hydroxyglutarate (D-2HG).

Biological & Genetic Profile

  • Origin: Derived from a 26-year-old male with anaplastic astrocytoma.

  • Key Mutations:

    • IDH1: Heterozygous mutation at Arg132His (p.R132H).

    • TP53: Homozygous mutation at Gly245Val (p.G245V).

    • ATRX: Nonsense mutation at Arg781Ter.


  • Metabolic Signature: Produces high levels of D-2-hydroxyglutarate (D-2HG), a driver of oncogenesis in gliomas.

Culture & Maintenance Guidelines
According to the BioVector? NTCC Inc. Technical Data Sheet, the standard handling procedures are:
  • Growth Mode: Adherent, though standard growth mode can vary depending on specific media.

  • Expansion Medium: Specifically formulated BioVector?TB096-2 Expansion Medium is recommended for maintenance.

  • Passaging:

    • Detachment: Use Accutase? (incubate at 37°C for 3–5 minutes) rather than standard Trypsin to ensure better viability.

    • Split Ratio: Typically 1:6 once the culture reaches 80% confluency.


  • Storage: Store in liquid nitrogen (–196°C). For freezing, use TB096 Expansion Medium supplemented with 10% DMSO.

  • Passage Limit: Verified to maintain marker expression and functionality for at least 10 passages after initial thawing.

Key Applications
  • Drug Screening: Developing therapies that modulate D-2HG production or target IDH1-mutated cells.

  • Mechanism Studies: Investigating the interplay between wild-type and mutated IDH1 alleles in astrocytoma progression.
