Molecular Weight Markers
Introduction to Molecular Weight Markers
A molecular-weight size marker is a general term for protein ladder, DNA ladder, or RNA ladder. These various molecular weight markers consist of a set of standards that are useful for identifying the approximate size and migration rate of a molecule following gel electrophoresis.
BioChain’s DNA ladders are prepared using highly specific molecular biology grade chemicals and our proprietary technology. Our 100-bp DNA Ladder Plus is a mixture of double-stranded DNA fragments with consistent sizes that display high accuracy. BioChain’s reference markers can be used on agarose or acrylamide gels to estimate the sizes of DNA fragments ranging from 75 to 3000 bp. We also make custom DNA ladders your specified sizes and concentration. Please contact us for more detail.
