What is ARMS PCR?

The Amplification Refractory Mutation System PCR (ARMS-PCR) is one of the most accurate tools in genetic disease diagnosis in recent days. It is a gold standard method for thalassemia and sickle cell anemia. Moreover, it is applicable in mutation detection of JAK2 and HIV.

How do you design PCR primer arms?

The primer is usually 30 bases in length. 2. The nucleotide at the 3′ end of the primer should be complementary to the target nucleotide i.e. G for C or C for G and T for A or A for T. Mismatch at this position can dramatically reduce the amplification.

What are arms primers?

The amplification-refractory mutation system (ARMS) is a simple method for detecting any mutation involving single base changes or small deletions. ARMS is based on the use of sequence-specific PCR primers that allow amplification of test DNA only when the target allele is contained within the sample.

What is ARMS PCR or allele specific PCR?

“A method used to detect a single base change or SNP using sequence-specific primers is referred to as ARMS or Allele-specific PCR.” The PCR technique can detect mutations like deletion, duplications, insertion or single base change- SNP.

How many primers are used in arms PCR?

four primers
The tetra-primer amplification refractory mutation system-polymerase chain (ARMS-PCR) reaction is a simple and economical method to genotype single-nucleotide polymorphisms (SNPs). It uses four primers in a single PCR and is followed just by gel electrophoresis.

What is Tetra arm primer?

The tetra-primer amplification refractory mutation system-polymerase chain (ARMS-PCR) reaction is a simple and economical method to genotype single-nucleotide polymorphisms (SNPs). It uses four primers in a single PCR and is followed just by gel electrophoresis.

How does a rifle primer work?

Upon being struck with sufficient force generated by the firing pin, or electrically ignited, primers react chemically to produce heat, which gets transferred to the main propellant charge and ignites it, and this, in turn, propels the projectile.

What is ARMS PCR and how does it work?

ARMS is based on the use of sequence-specific PCR primers that allow amplification of test DNA only when the target allele is contained within the sample. Following an ARMS reaction the presence or absence of a PCR product is diagnostic for the presence or absence of the target allele.
