Invitrogen 50 bp DNAラダーは、50 bp～2,500 bpの範囲の二本鎖DNAのサイジングおよび近似定量用に設計されています。50 bp DNAラダーは、クロマトグラフィーで精製された17個のDNA断片で構成されており、2500、800、および350 bpの基準バンドを有しているため、簡単に配向できます。

50 bp DNAラダーは、2%アガロースゲルでの分離に最適です。

50 bp DNAラダーの特長：
•鋭利で透明なバンド—クロマトグラフィー精製断片により、一貫性と信頼性の高い結果を提供
• 利便性—DNAの移動を追跡する6X TrackItシアン／オレンジローディングバッファーを提供
• 正確—各バンドで正確な量のDNA

製品用途
二本鎖DNAラダーは、エチジウムブロマイドまたはSYBR Safe染色後に2%のアガロースゲルで可視化できます。ラダーは、均一な強度のDNAバンドで設計されており、各バンドをはっきりと確認できます。各バンド内の正確なDNA量により、DNAサンプルの近似定量が可能になります。

このラダーは、T4ポリヌクレオチドキナーゼまたはT4 DNAポリメラーゼで放射性標識できます。

研究用にのみ使用できます。診断用には使用いただけません。

よくあるご質問（FAQ）

Can I know the sequences of Invitrogen DNA ladders?

Sequences of Invitrogen DNA and RNA ladders are proprietary.

Are Invitrogen DNA ladders composed of linear or circular/supercoiled DNA?

Invitrogen DNA ladders contain linear dsDNA fragments.

Are Invitrogen DNA ladders composed of single-stranded or double-stranded DNA fragments?

Invitrogen DNA ladders are composed of double-stranded DNA fragments only.

I'm seeing anomalous migration of my DNA ladder. What happened?

This can happen if the marker was heated. Please ensure that the ladders are not heated before use.

What is the difference between the TrackIt DNA Ladders and other DNA ladders?

TrackIt DNA Ladders contain two tracking dyes in the sample buffers, which serve as visual markers for tracking electrophoresis progress through the gel, and also to indicate when maximum resolution is achieved. The tracking dyes should not obscure your visualization of DNA bands in the ladder, as the dyes run outside the limits of most DNA bands in the ladder.

TrackIt Cyan/Orange Loading Buffer is formulated with unique tracking dyes, Xylene Cyanol FF and Orange G. We recommend TrackIt Cyan/Orange Loading Buffer for DNA fragments between 10 bp and 1 kb.

The TrackIt Cyan/Yellow Loading Buffer is formulated with unique tracking dyes, Xylene Cyanol FF and Tartrazine. We recommend TrackIt Cyan/Yellow Loading Buffer for DNA fragments between 100 bp and 10 kb. The molecular weights are Xylene Cyanol FF, 638.6; Orange G, 452.4; Tartrazine, 534.4.

Note: The TrackIt DNA Ladders are not recommended for use with polyacrylamide gels and are not designed for quantitation.

Abstract
ChIP-Seq using high-throughput DNA sequencing for genome-wide identification of transcription factor binding sites.
Authors:Lefrançois P, Zheng W, Snyder M
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 ... More

'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 ... More
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.

'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.

'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.

Identification of novel mutation in cathepsin C gene causing Papillon-Lefèvre Syndrome in Mexican patients.
Authors:Romero-Quintana JG, Frías-Castro LO, Arámbula-Meraz E, Aguilar-Medina M, Dueñas-Arias JE, Melchor-Soto JD, Romero-Navarro JG, Ramos-Payán R
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 ... More
