Invitrogen 50 bp DNA 分子量标准设计用于 50 bp 至 2,500 bp 内双链 DNA 片段的大小鉴定和近似定量。50 bp DNA 分子量标准由 17 个层析纯化的个体 DNA 片段组成，参比条带分别为 2500、800 和 350 bp，便于轻松定向。
50 bp DNA 分子量标准非常适合利用 2% 琼脂糖凝胶进行 DNA 片段分离。
50 bp DNA 分子量标准的特点：
•明显、清晰的条带—层析纯化片段可获得一致和可靠的结果
• 便利—已经预混了 6X TrackIt Cyan/Orange 上样缓冲液，便于追踪样品 DNA 迁移
• 精确—可获得每条带中的 DNA 精确量
产品用途
溴化乙锭或 SYBR Safe 染色后，可在 2% 琼脂糖凝胶上观测到双链 DNA 分子量标准。该分子量标准设计有强度均匀的 DNA 条带，便于清楚查看每一条带。每个条带中确切量的 DNA 可实现样品 DNA 近似定量。
该分子量标准可使用 T4 多聚核苷酸激酶或 T4 DNA 聚合酶进行放射性标记。

Abstract
ChIP-Seq using high-throughput DNA sequencing for genome-wide identification of transcription factor binding sites.
Journal:Methods Enzymol
PubMed ID:20946807
'Much of eukaryotic gene regulation is mediated by binding of transcription factors near or within their target genes. Transcription factor binding sites (TFBS) are often identified globally using chromatin immunoprecipitation (ChIP) in which specific protein-DNA interactions are isolated using an antibody against the factor of interest. Coupling ChIP with high-throughput
Post intrastromal corneal ring segments insertion complicated by Candida parapsilosis keratitis.
Journal:Clin Ophthalmol
PubMed ID:23467516
'This case report describes the clinical and histopathologic features, including molecular confirmation, of fungal keratitis after intrastromal corneal ring segments placement for keratoconus. A 52-year-old woman underwent insertion of Intacs(®) corneal implants for treatment of keratoconus. Extrusion of the implants was noted 5 months post insertion and replaced. Three months
Development of PCR-RFLP assay for the discrimination of Plasmodium species and variants of P. vivax (VK210, VK247 and P. vivax-like) in Anopheles mosquitoes.
Journal:Acta Trop
PubMed ID:21420375
'The identification of Plasmodium species in Anopheles mosquitoes is an integral component of malaria control programs. We developed a new assay to identify Plasmodium falciparum, Plasmodium malariae, and Plasmodium vivax variants. Specific primers were designed to hybridize to CS gene-specific regions. Polymerase chain reaction (PCR) and restriction fragment length polymorphism
Report of an international collaborative study to evaluate the suitability of multiplex PCR as an identity assay for different sub-strains of BCG vaccine.
Journal:Vaccine
PubMed ID:20732463
'Current methods for the identification of BCG vaccine in quality control settings involve acid-fast staining with microscopic examination. However, this method is unable to distinguish the many different sub-strains of BCG, or to differentiate BCG strains from virulent members of the Mycobacterium tuberculosis complex. A multiplex PCR (mPCR) which uses
Identification of novel mutation in cathepsin C gene causing Papillon-Lefèvre Syndrome in Mexican patients.
Journal:BMC Med Genet
PubMed ID:23311634
Papillon-Lefèvre Syndrome (PLS) is a type IV genodermatosis caused by mutations in cathepsin C (CTSC), with a worldwide prevalence of 1-4 cases per million in the general population. In México, the prevalence of this syndrome is unknown, and there are few case reports. The diagnosis of twenty patients in the
