ProxiB 100bp DNA Ladder: A Precise Tool for Accurate DNA Sizing

The ProxiB 100bp DNA Ladder is a pre-stained molecular weight marker designed for precise and reliable sizing of double-stranded DNA fragments during agarose gel electrophoresis. This robust tool caters to the needs of researchers in various fields of molecular biology and biotechnology.

Straightforward Procedure for Laboratory Production of DNA Ladder

Key Features:

  • Accurate Banding Pattern: The ladder comprises a set of 10 sharp, tightly spaced bands ranging from 50bp to 1000bp. This ensures excellent resolution, allowing for clear differentiation of even closely sized DNA fragments.

  • Pre-stained Convenience: The ladder is pre-stained with a carefully chosen dye, eliminating the need for additional staining steps and minimizing handling time. The dye exhibits high sensitivity and compatibility with various detection methods like UV illumination and fluorescence imaging.

  • Broad Range: The ladder covers a broad size range from 50bp to 1000bp, making it suitable for analyzing a wide variety of DNA fragments, from small PCR products to larger plasmids.


  • Sizing DNA Fragments: The ProxiB 100bp DNA Ladder is ideal for accurately determining the size of DNA fragments generated by various techniques such as PCR, restriction enzyme digestion, and DNA shearing.

  • Monitoring DNA Integrity: The presence and relative intensity of bands in the ladder can be used to assess the overall integrity of DNA samples by identifying potential degradation products like smears or missing bands.

  • Gel Electrophoresis Optimization: The ladder can be used to optimize gel electrophoresis conditions, such as agarose concentration and running time, to achieve optimal resolution and separation of DNA fragments.

Structured Format:

ProxiB 100bp DNA Ladder is supplied in a convenient, ready-to-use format. The ladder is typically provided in a Tris-acetate-EDTA (TAE) buffer solution and may include a loading dye for easy sample visualization during gel loading.  Additionally, some manufacturers might offer the ladder in different quantities to suit varying laboratory needs.

Overall, the ProxiB 100bp DNA Ladder provides a valuable tool for researchers by offering accurate and reliable DNA sizing, ease of use, and broad applicability in various molecular biology techniques.
