Product Description

Aladdin's UltraBio™ Red Fluorescent DNA Ladder (0.2-12kb, 12 bands, Red) is supplied in a ready-to-use format containing NA-Red (Nucleic Acid Red) fluorescent stain and Red tracking dye. It consists of 12 DNA fragments ranging from 200bp to 12kb and can meet the molecular weight reference needs for most regular DNA electrophoresis analysis.This product is optimized for direct loading into unstained agarose gels and is recommended for use as a molecular weight reference for DNA samples loaded by UltraBio™ Red Fluorescent DNA Loading Buffers .The fluorescence intensity of the 2000bp fragment is three times higher than others, making the ladder bands easier to be differentiated. The content of each ladder fragment is shown on the right side of the Figure, allowing the estimation of both size and concentration of DNA fragments on agarose gels.This product uses the improved version of Red as an indicator for easy visual loading and tracking of DNA migration during electrophoresis.Red fluorescence of this product is detected at a wavelength of about 300nm which is very close to the excitation and emission light of EB. Gel Imager used for EB detection can be used directly for the observation of this product without changing filters or other observation devices.Loading 5μl of DNA Ladder per lane is sufficient to visualize all fragments of the ladder.

Precautions：

This product should be kept in the dark. Exposure to regular indoor light during the electrophoresis does not change its performance.Freshly prepared agarose gel and electrophoresis buffer are recommended to obtain the best separation result.When smear or unsatisfactory band separation is observed, the following methods can be attempted: use freshly prepared electrophoresis buffer; reduce the loading amount of DNA; reduce the agarose concentration; use a longer gel; decrease the voltage for electrophoresis and extend the time of electrophoresis to improve DNA separation, etc.This product is compatible with commonly used electrophoresis buffers, such as TAE and TBE.This product is for R&D only. Not for drug, household, or other uses.For your safety and health, please wear a lab coat and disposable gloves during the operation.

Instructions for Use：

1. Prepare agarose gel with an appropriate concentration. Do not add any dye to the gel.2. Mix the DNA Ladder well before use. Load 5μl of DNA Ladder per lane onto the agarose gel for electrophoresis. Note: When Red interferes with the observation of target DNA fragments, please use Red Fluorescent DNA Ladder (0.2-12kb, 12 bands, Bromohenol Blue).3. After electrophoresis, use a Gel Imager System for observation or taking photos.
