DNA Marker (100-700 bp) with TBE & Loading Dye
DNA Marker (100-700 bp) with TBE & Loading Dye
Ready-to-load DNA marker with seven bands from 100–700 bp, supplied with Loading Buffer [10X] and TBE Buffer [10X] for agarose gel electrophoresis.
For Research Use Only.
Overview
Run, track and size small DNA fragments with a marker that goes straight into the well.
This kit provides the three essential reagents for routine agarose gel electrophoresis of DNA fragments in the 100–700 bp range. The DNA marker contains seven linear double-stranded DNA fragments at 100, 200, 300, 400, 500, 600, and 700 bp.
The marker also comes premixed with loading buffer, so you can load it directly with no mixing or extra pipetting. The electrophoresis bands are clear, facilitating accurate determination of the DNA content of the target band. When in use, take 5-10 µL and it can be directly used for gel electrophoresis. Paired with a concentrated TBE buffer [10X] and a Gel Loading Buffer [10X] for your samples, it takes you from sample to sized bands quickly and consistently.
Each kit contains two 1 mL tubes of Loading Buffer [10X]. Combine the loading buffer with the DNA sample to achieve a 1X final concentration, then mix thoroughly and load the sample for agarose gel electrophoresis.
Band Pattern & Gel Image
Within the DNA Marker, the 500 bp fragment is intentionally enhanced for easy identification and produces a brighter band. This fragment contains 100 ng DNA per 5 µL, whereas each of the remaining DNA fragments contains 50 ng per 5 µL.

Features & Applications
Ready-to-load marker
It is premixed with loading buffer, so you pipette it straight into the well. This saves time and removes a source of mixing errors.
Complete workflow
One kit covers gel casting, sample loading and size determination.
Optimized for small fragments
The 100–700 bp range covers typical PCR amplicons, colony PCR products and restriction fragments.
Clear, easy-to-read bands
Well-resolved reference bands make size estimates quick and reliable.
Concentrated, economical formats
The 10X sample loading buffer and concentrated TBE stock are diluted before use, so each kit goes further.
Sharp bands, stable runs
TBE has greater buffering capacity than TAE and heats less, so it holds pH through long runs and tolerates higher voltages without band distortion.
Applications
- Verification of PCR and RT-PCR products
- Analysis of restriction enzyme digests
- Colony PCR screening
- DNA fragment size estimation
- Teaching labs and routine molecular biology training (For Laboratory Use Only. Not for Clinical Use).
