产品信息
产品描述 肌动蛋白破坏(Actin disruption)可用来研究细胞功能,体外如迁移和内吞,体内如肿瘤细胞迁移。 红海海绵素A(Latrunculin A,LAT-A),CAS NO. 76343-93-6,是一种分离自红海海绵Latrunculia magnifica,具有生物活性的2-噻唑烷酮大环内酯天然产物,隔离单体肌动蛋白(G-actin)和防止肌动蛋白丝(F-actin)组装。LAT-A按照1:1化学计量结合单体肌动蛋白,体外(Kd=0.2μM)和细胞内(Kd=0.5μM,30min)都可用来阻断肌动蛋白聚合。LAT-A(1-10μM)处理10min内可引起肿瘤细胞骨架去聚合。LAT-A(10μM)过夜处理细胞能强烈抑制肌动蛋白合成。延长处理细胞能阻断地塞米松诱导的肌动蛋白骨架变化,但不影响细胞活力。LAT-A能抑制肿瘤细胞生长,对A549,H522-T1, HT-29,U-937和MDA-MB-43细胞的IC50分别是142,142,142,166和95 nM。比红海海绵素B(LAT-B)的活性更强。 我司提供两种形式的LAT-A: 一种以DMSO储存液形式提供,浓度为5mM,对应货号为MZ5809-50UG和MZ5809-100UG。 一种以冻干粉形式提供,对应货号为MZ5809-500UG。

保存与运输方法 保存:-20ºC避光干燥保存,其中DMSO储存液至少1年有效,冻干粉至少2年有效。 运输:冰袋运输。
使用方法 1) 对于DMSO储存液(货号:MZ5809-50UG,MZ5809-100UG),浓度为5mM。由于量比较少,务必要将储存液置于室温回温至少30min,或借助25℃温育使其完全融化,低速离心后再开盖。如果用户优化所得的最佳工作浓度比较低,亦可用高质量无水DMSO将本储存液稀释到一中间浓度(比如:1mM),再根据单次用量分装冻存。前提是确保最终工作体系内残留的DMSO终浓度<0.1%,最高不要超过0.5%。 2) 对于冻干粉(货号:MZ5809-500UG),于室温回温至少20min,低速离心后,加入乙醇或DMSO配置所需浓度的储存液。两者的溶解性约为25mg/ml。 3) 于实验前,将适量储存液用生理缓冲液或生理盐水稀释到所需的工作浓度。具体的工作浓度请根据实验要求参考文献来摸索。【注意】:工作液现配现用。
注意事项 1)红海海绵素A(LAT-A)据报道对光敏感,建议避光保存,且保持干燥。 2)为了您的安全和健康,请穿实验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?
