Telomeres are repetitive nucleotide elements at the ends of chromosomes that protect chromosomes from degradation and genetic information loss. Normal diploid cells lose telomeres with each cell cycle. Telomere length, therefore, decreases over time and may predict lifespan. Telomere shortening has negative effects on health conditions and has been linked to many health issues including aging and cancer. Accurate and consistent quantification of telomere length is important in many aspects of cell biology such as chromosomal instability, DNA repair, senescence, apoptosis, cell dysfunctions, and oncogenesis.
ScienCell's Absolute Rat Telomere Length Quantification qPCR Assay Kit (ARTLQ) is designed to directly measure the average telomere length of a rat cell population. The telomere primer set recognizes and amplifies telomere sequences. The single copy reference (SCR) primer set recognizes and amplifies a 100 bp-long region on rat chromosome 17, and serves as reference for data normalization. The reference genomic DNA sample with known telomere length serves as a reference for calculating the telomere length of target samples. The carefully designed primers ensure: (i) high efficiency for trustworthy quantification; and (ii) no non-specific amplification. Each primer set has been validated by qPCR with melt curve analysis and gel electrophoresis for amplification specificity and by template serial dilution for amplification efficiency.
端粒(Telomeres)是位于染色体末端的重复核苷酸序列,可保护染色体免于降解并防止遗传信息丢失。在正常的二倍体细胞中,端粒会随着每一次细胞分裂而逐渐缩短。因此,端粒长度会随时间逐渐减少,并可能与细胞寿命相关。端粒缩短会对健康状况产生不利影响,并与多种疾病相关,包括衰老和癌症等。在细胞生物学研究中,对端粒长度进行准确且稳定的定量,对于研究染色体不稳定性、DNA 修复、细胞衰老、细胞凋亡、细胞功能异常以及肿瘤发生等过程具有重要意义。
ScienCell 大鼠端粒绝对长度定量 qPCR 检测试剂盒(ARTLQ)旨在用于直接测定大鼠细胞群体的平均端粒长度。试剂盒中的端粒引物组可特异性识别并扩增端粒序列。单拷贝参考基因(SCR)引物组用于识别并扩增大鼠第 17 号染色体上一段约 100 bp 的序列,并作为数据归一化的参考。试剂盒中提供的已知端粒长度的参考基因组 DNA 样本,可作为标准用于计算目标样本的端粒长度。精心设计的引物确保:(i) 具有较高的扩增效率,从而实现可靠的定量;(ii) 无非特异性扩增。每套引物均通过 qPCR 熔解曲线分析和凝胶电泳验证其扩增特异性,并通过模板梯度稀释实验验证其扩增效率。
