Ionomycin is a Calcium ionophore and an antibiotic produced byStreptomyces conglobatusATCC 31005. It is observed that LCLC 103H cells overexpressing the catalytic subunit of μ-calpain rapidly underwent cell death after treatment with ionomycin. The first signs of Ionomycin-induced cell death are detected 3 h after addition of the ionophore. Addition of 2 μM Ionomycin to LCLC 103H cells causes an instantaneous increase in intracellular Ca2+concentration from 50 to 180 nM. Remarkably, calcium concentrations are raised transiently to 0.8-1.5 μM. DNA and protein analysis in Ionomycin-treated cultures revealed DNA fragmentation and PARP cleavage to an 85-kDa fragment typical of caspase-mediated apoptosis. Three hours after addition of ionomycin, the percentage of early apoptotic cells approximately doubles. Necrosis could be detected in ~1-5% of the Ionomycin treated cells as supported by simultaneously positive fluorescein labeling and propidium iodide uptake. Caspase activation in whole cells was followed by monitoring the increase in activity against Ac-DEVD-amc following Ionomycin treatment.
Gendepot在脊椎动物中，已经鉴定出3个主要的肌动蛋白同种型，即α，β和γ。α肌动蛋白存在于肌肉组织中，是收缩装置的主要组成部分。在大多数细胞类型中，β和γ肌动蛋白作为细胞骨架的成分和内部细胞运动的介质共存。β肌动蛋白是高度保守的蛋白，参与细胞运动，结构和完整性。β肌动蛋白是细胞质蛋白。抗肌动蛋白是一种上样对照抗体，对于正确理解您的蛋白质印迹至关重要。β-肌动蛋白加载控制抗体用于通过确认整个凝胶上的蛋白加载均匀来标准化检测到的蛋白水平。 参考文献（0）
