DNA, RNA and protein molecular weight ladders for accurate gel-band assignment
Pre-stained and unstained DNA, RNA, and protein molecular weight ladders for gel electrophoresis. Quality drives gel-band assignment accuracy.
Pick by application and convenience.
- Size range. Low-range for fragments under 500 bp. Broad-range for routine. Ultra-high MW for plasmid backbones.
- Pre-stained versus unstained. Pre-stained shortens workflow. Unstained may give cleaner band edges.
- Reference band intensity. Intense reference bands at common reference sizes give faster visual approximation.
- Application. DNA, RNA, protein each have specific ladders. Match to your gel type.
Norgen Biotek and Meridian (Bioline) cover the standard ladder catalogue.
