01General information
- Description
MM.1S-Luc 是人類多發性骨髓瘤細胞系 MM.1S 的基因改造衍生物。此經工程改造的變異株能穩定表達螢火蟲螢光素酶(Luc),使其適用於體內生物發光成像及臨床前篩選應用。 其親本 MM.1S 細胞系源自一名多發性骨髓瘤患者,其特徵為對糖皮質激素敏感,並常被用於針對血液惡性腫瘤(尤其是涉及漿細胞異常的病變)的臨床前研究。
螢火蟲螢光素酶的導入使非侵入性生物發光成像成為可能,讓研究人員能夠在活體動物模型中動態監測腫瘤負荷與進展。 這在異種移植研究中尤為有利,在該類研究中,MM.1S-Luc 可用於評估治療療效、腫瘤植入動力學及轉移情況,並為在各種實驗條件下量化腫瘤細胞提供了一個平台。

- GMO status details
- GMO-S1: This cell line contains a stably integrated firefly luciferase reporter cassette (Luc2, codon-optimized) introduced via replication-incompetent lentiviral transduction. The resulting polyclonal cell population was maintained under puromycin selection (1–5 µg/mL). S1 containment is required. This classification applies only within Germany and may differ elsewhere.

- Thawing and culturing
Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.
Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.
For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.
Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.
Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.
Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.
Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.
Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.
06Quality control and cryopreservation
- Sterility
透過基於 PCR 的檢測及基於發光原理的支原體檢測方法,排除支原體污染的可能性。
為確保無細菌、真菌或酵母菌污染,每日均會對細胞培養物進行目視檢查。
- Freeze medium
- 作為冷凍保存培養基,我們使用完全生長培養基(含 FBS)+ 10% DMSO 以確保解凍後的存活率,或使用 CM-1 (Cytion 型號 800100),該培養基含有經優化的滲透保護劑和代謝穩定劑,可提升細胞恢復率並減輕冷凍誘導的壓力。
- Storage conditions
若需長期保存,請將試管置於溫度約為 −150 至 −196 °C 的氣相液氮中。僅在轉移至液氮之前,可將試管暫時存放於 −80 °C 環境中,作為短期過渡步驟。
- Shipping conditions
冷凍保存的細胞系會以乾冰冷藏,並裝於經驗證的隔熱包裝中,包裝內含有足夠的冷媒,以確保在運輸過程中溫度維持在約 −78 °C。收到貨物後,請立即檢查容器,並盡快將試管轉移至適當的儲存場所。

08Legal and safety
- Safety precautions
- 若計劃將低溫試管存放在液態氮中以供日後解凍,必須嚴格遵守相關安全措施。 必須穿戴適當的防護手套和防護服,且在將冷凍樣本移入或移出液氮罐時,必須佩戴口罩或安全護目鏡。此舉旨在降低因取出時冷凍試管可能發生爆炸而導致受傷的風險,此類爆炸可能造成尖銳碎片飛濺。
