细胞衰老是参与正常胚胎和成年生活的生物过程,并随着年龄的增长而增加。它也发生在各种疾病的机制内和治疗干预之后。衰老细胞的检测和测量在研究和临床实践中至关重要且非常需要。衰老细胞存在于广泛的年龄相关疾病中,包括癌症。SenTraGor™是一种与生物素偶联的SBB类似物,与已被证明在衰老过程中积累的脂褐素颗粒发生反应。
SenTraGor™ (GL13) 是一种用于检测衰老的创新试剂。衰老细胞在正常发育、组织稳态、衰老和广泛的年龄相关疾病中起着重要作用。到目前为止,衰老领域的一个主要问题是缺乏可靠的标记物来特异性检测这些细胞,尤其是原位细胞。SenTraGor™ (GL13) 是一种生物素化的苏丹黑 B 基化学试剂,旨在克服这一限制。
SenTraGor™ (GL13) 染色可以检测任何生物材料中的衰老。衰老细胞的直接可视化可以在所有档案组织标本(福尔马林固定石蜡包埋)和来自活检或细胞培养物的细胞中实现。
产品溶解
每个小瓶含有20毫克(货号:AR8850020)固体SenTraGor™化合物。要溶解化合物,分别加入3.5-3.75ml的100%乙醇,并用封口膜覆盖。理想的浓度取决于所检查的生物材料及其加工过程,可以按如下方式确定:从3.5ml体积的100%乙醇开始。如果观察到试剂的非特异性(“背景”)反应,则分别将体积调整为3.75ml。在56°C的水浴中孵育120分钟,直到化合物完全溶解。使用前,使用13毫米过滤器和0.22μm膜用注射器过滤。
产品存储
在室温下储存。避光。
溶解后在室温下储存,防止光线和保持密封。该试剂在室温下溶解后可稳定长达 2 个月。或者分装,确保密封,避光并在室温下储存可长达8个月。
实验对照
a.Positive controls:
Cellular systems that can be used as positive controls are cells undergoing replicative senescence(RS), for example primary human diploid lung fibroblasts (DLFs) at late passages of division or cellsexhibiting Stress induced senescence (SISP), for example irradiated primary human DLFs, or inducibleSaos2 p21WAF1/CIP1 Tet-ON cells, when p21WAF1/CIP1 is activated. Tissues from animal modelsand human clinical cases with established senescence can serve as positive controls (examples: K-RAS induced mouse lung adenomas, irradiated human laryngeal lesions).
b.Negative controls:
Cellular systems that can be used as negative controls are early proliferative passages of primaryhuman DLFs, Saos2 p21WAF1/CIP1 Tet-ON cell when p21WAF1/CIP1 is OFF (not induced). Normal,non-aged, tissues can be used as negative controls.
