What is MSP PCR?

Table of Contents

Methylation-specific PCR (MS-PCR or MSP) is one of the most commonly used methods for gene/sequence-specific detection of DNA methylation. The DNA undergoes bisulfite conversion of cytosine to uracil and then the methylated sequences are selectively amplified with primers specific for methylation.

Can PCR detect methylation?

PCR-based methods are routinely used to study DNA methylation on a gene-specific basis, after bisulfite treatment.

What is the difference between Methylation Specific PCR and genome bisulfite sequencing?

The main difference between BS and MSP primers is that the later are designed to selectively amplify a DNA región based on its methylation status, they deliverately contain CpG dinucleotides within their sequence in order to give a signal if a certain condition is met (e.g. ATTACCACG will work only if the “C” in the …

How is DNA methylation detected?

Currently, there are three primary methods to identify and quantify DNA methylation. These are: sodium bisulfite conversion and sequencing, differential enzymatic cleavage of DNA, and affinity capture of methylated DNA (1). Restriction enzyme based differential cleavage of methylated DNA is locus-specific.

What is the difference between Methylation-Specific PCR and genome bisulfite sequencing?

How is methylation test done?

Methylation metabolites are measured in plasma, and genetic single nucleotide polymorphisms (SNPs) are analyzed via buccal swab. The results are synthesized on a front-page Interpretation-at-a-Glance (IAAG) graphic for quick methylation status assessment.

What is a methylation report?

The Methylation test examines genes involved in five sub-cycles – folate, methionine, neurotransmitter, transsulphuration and urea.

How do you design primers for Methylation-Specific PCR?

Finessing the Design of Methylation-Specific PCR Primers

Design primers to the bisulfite-converted template.
Make sure there are non-CpG C’s in the target sequence.
Aim for six to seven CpG’s.
Keep the targets short.
Obey the rules of PCR.
Use the appropriate computer program.

How do you make MSP primers?

Below are Herman’s tips for successful MSP primer design.

Design primers to the bisulfite-converted template.
Make sure there are non-CpG C’s in the target sequence.
Aim for six to seven CpG’s.
Keep the targets short.
Obey the rules of PCR.
Use the appropriate computer program.

Is PCR amplified DNA methylated?

PCR-based techniques are routinely used to study DNA methylation following the treatment of DNA with sodium bisulphite. This treatment involves the deamination of cytosines to uracil which are then converted to thymine in subsequent PCR amplification.
