產品信息
產品描述: 肌動蛋白破壞(Actin disruption)可用來研究細胞功能,體外如遷移和內吞,體內如腫瘤細胞遷移。
紅海海綿素B(Latrunculin B,LAT-B),CAS NO.76343-94-7,是一種分離自紅海海綿Latrunculia magnifica,具有生物活性的2-噻唑烷酮大環內酯天然產物,引起細胞形狀和肌動蛋白組織發生濃度依賴性的變化。LAT-B能隔離單體肌動蛋白(G-actin)和防止肌動蛋白絲(F-actin)組裝。按照1:1化學計量結合單體肌動蛋白,體外和細胞內(Kd=60nM)都可用來阻斷肌動蛋白聚合。雖然LAT-B的活性稍微弱于LAT-A,但其短期效應與LAT-B相當。在一直含LAT-B的培養基內血清的存在逐漸引起LAT-B失活,以致于誘導的變化是瞬時的。正因如此,與LAT-A相比,LAT-B可能產生更少不想要的生理效應,使其更適合短期研究。
我司提供兩種形式的LAT-B,一種以DMSO儲存液形式提供,貨號MZ5810-100UG。一種以凍干粉形式提供,對應貨號為MZ5810-1000UG。

保存與運輸方法 保存:-20oC避光保存,其中DMSO儲存液1年有效,凍干粉2年有效。 運輸:冰袋運輸。
使用方法
1) 對于凍干粉(貨號:MZ5810-1000UG),于室溫回溫至少20min,低速離心后,加入乙醇或DMSO配置所需濃度的儲存液。兩者的溶解性達50mM。 2) 對于DMSO儲存液(貨號:MZ5810-100UG),濃度為10mM。使用前請室溫回溫至少20min,低速離心,再進行后續操作。由于本身液體量比較少,保存過程中蓋子要密封。也可以根據實際需要工作濃度,將本儲存液用DMSO稀釋到一個中間濃度,比如2mM。然后再進行后續操作。 3) 于實驗前,將適量儲存液用生理緩沖液,培養基或生理鹽水稀釋到所需的工作濃度。具體的工作濃度請根據實驗要求參考文獻來摸索?!咀⒁狻浚汗ぷ饕罕仨毈F配現用。
注意事項 1)紅海海綿素B(LAT-B)據報道對光敏感,建議避光保存,且保持干燥。 2)為了您的安全和健康,請穿實驗服并戴一次性手套操作。

BMC Biol 22, 244 (2024). https://doi.org/10.1186/s12915-024-02045-2 Pharmacological treatment For continuous immersion treatment, zebrafish larvae at 6 dpf with single axon injury were exposed to 10, 20, or 50 μM latrunculin B (76343–94-7, Maokang, China) for 48 h until imaging for axon regeneration. The immersion medium was replaced every 24 h to maintain the effectiveness of the drug. The control group was treated with an equivalent concentration of DMSO (D12345, Thermo Fisher, USA).
Hello,
Our lab dissolved one vial of BODIPY? 558/568 C12 (D3835 Lot:2581655) with 529.2ul fresh DMSO (MP biomedical, 196055, 100ml) to prepare 4mM stock solution, and aliquoted into 10-20ul EP tubes, and stored at -20℃ in aluminum foil bag this March. It worked well for trafficking fatty acid for original two-cycles experiment.
However, when we restarted the experiment this November, we found the color of some aliquots turned into purple-red not the original pink (see below Fig-1). We choose one aliquot with normal pink color to perform same experiment (same cells and experiment condition), we cannot find fatty acid transfer signal. (see below Fig-2).
Fig-1 Color of stock solution, left (blue arrow)-Color turned into purple-red; right (red arrow)-color looked similar to first use.
Fig-2 Upper row was the staining pattern taken on March. Lower row was one taken on November. Do you think the bad results caused by loss activity of stock solutions?
