Product Description

YALEPIC® 8K DNA Marker consists of 10 double-stranded DNA fragments of specific molecular weight and is mixed with 1×loading buffer containing a blue dye, which can be used as standard reference in agarose gel electrophoresis.  All the fragments in the DNA Marker/Ladder are obtained by enzymatic digestion and purification. The bands are more clear during electrophoresis and the mass ratio between the bands is more accurate. The 750 bp fragment at  concentration of 100 ng/5 μl, which are bright bands; 1500bp fragment at  concentration of 40 ng/5 μl;all the remaining fragments are at a concentration of 50 ng/5 μl.

Bands: 100bp,250bp,500bp,750bp,1000bp,1500bp,2000bp,3000bp,5000bp,8000bp.

Features

  • Reliable results: Electrophoretic bands are Sharp and clear.
  • Convenient: Provided with Gel Loading Buffer for tracking of sample DNA migration.
  • Precise: Exact molecular weight of DNA in each band.

Storage

Store at -30 ~ -15°C for 3 years,at 2~8 ℃ for one year; transport at -20 ~ 30℃.

Is the YALEPIC 8K DNA Marker ready-to-use? Does it need additional Loading Buffer?

Yes, this is a ready-to-use product, pre-mixed with 1x Loading Buffer. Simply load 5 microL directly for agarose gel electrophoresis – very convenient and quick.

What is the band composition and concentration of the 8K DNA Marker?

This product consists of 10 double-stranded DNA fragments: 100 bp, 250 bp, 500 bp, 750 bp, 1000 bp, 1500 bp, 2000 bp, 3000 bp, 5000 bp, 8000 bp. The 750 bp band is at 100 ng/5 microL (bright band); 1500 bp at 40 ng/5 microL; all other bands at 50 ng/5 microL.

Which electrophoresis types is the 8K DNA Marker suitable for?

This product is suitable for agarose gel electrophoresis, not recommended for polyacrylamide gel electrophoresis (PAGE). For high-resolution double-stranded DNA analysis in polyacrylamide gels, use a dedicated PAGE DNA Marker.

How to store the 8K DNA Marker? How long can it be stored?

Store at 2-8 degrees C for 2 years, or -20 degrees C for 3 years. Avoid repeated freeze-thaw. Do not heat. Transport with ice packs.

What causes blurry or unclear bands during electrophoresis?

Common causes and solutions: (1) Stale electrophoresis buffer – reduced ion concentration and elevated pH cause blurry bands; replace with fresh buffer. (2) Improper gel preparation – ensure agarose is fully dissolved; allow gel to set completely (30-60 minutes). (3) Improper loading volume – try diluting 2-3x with water and loading 8-10 microL.

Is the 8K DNA Marker compatible with GelRed, SYBR Green, and other fluorescent dyes?

Yes, compatible with GelRed, SYBR Green, EB, and other common DNA fluorescent dyes in standard agarose gel electrophoresis staining systems.

How to prevent DNA Marker band degradation or tailing?

Band degradation or tailing is typically caused by nuclease contamination. Use nuclease-free pipette tips and centrifuge tubes for aliquoting, avoid repeated freeze-thaw, and maintain aseptic technique during operation.

What are the advantages of YALEPIC 8K DNA Marker compared to other brands?

This product is prepared by restriction digestion of plasmid DNA, providing higher molecular weight accuracy, clearer and sharper bands, cleaner background, and excellent batch-to-batch stability compared to PCR product-mixed markers. The ready-to-use pre-mixed Loading Buffer design also saves preparation time.

Can the 8K DNA Marker be used as a molecular weight reference for RNA electrophoresis?

Not recommended. DNA Markers are double-stranded DNA molecules; in RNA denaturing gel electrophoresis, double-stranded structures will denature, making size indication inaccurate. For RNA molecular weight reference, use a dedicated RNA Marker. However, for rough observation in standard agarose gel electrophoresis, it can be used approximately.

What application scenarios is this product suitable for?

Suitable for PCR product identification, restriction fragment size analysis, genomic DNA fragment estimation, plasmid DNA identification, and other common molecular biology experiments. Covers a wide molecular weight range of 100-8000 bp, meeting most routine DNA fragment analysis needs.
