Improve adhesion of dissimilar materials such as polymers to inorganic substrates. Also called primers. Primers generally contain a multifunctional chemically reactive species capable of acting as a chemical bridge. In theory, any polar functional group in a compound may contribute to improved bonding to mineral surfaces. However, only a few organofunc-tional silanes have the balance of characteristics required... 

PCR a technique for making many copies of a specific DNA sequence. The reaction is initiated using a pair of short primer sequences which match the ends of the sequence to be copied. Thereafter, each cycle of the reaction copies the sequence between the primers. Primers can bind to the copies as well as the original sequence, so the total number of copies increases exponentially with time. 

Primers, primer materials and detonators should never he stored with other high explosives. A separate building or annex to an explosive store is usually desirable for keeping detonators. Similarly, black powder must also be kept in separate locations away from high explosives. 

The constituents of a 25-pl PCR mixture in a standard 200-pl tube are given in Table 8.2.2. Volumes can be easily adjusted proportionally for larger or smaller PCR volumes. The PCR conditions depend primarily on the melting characteristics of the primers (primers with a low melting temperature require relatively low annealing... 

Blowback An escape of gas under press to the rear, on firing small-arms or fixed or semi-fixed artillery ammunition, is called a blowback. This may be caused by ruptured cartridge, pierced primer, primer leak, blown primer or primer set -back. The term also applies to the recoil of an unlocked bolt in a firearm Refs 1)TM 9-1910( 1955),p 231 2)Glossary of Ord(1959),39...

A closer examination of the Okazaki fragments led to detection of short stretches of ribonucleotides at the 5 ends. From this and many other observations on different systems it was determined that a new DNA chain can be initiated only by attaching the first deoxynucleotide through its 5 -phosphate to the 3 -OH of a short RNA polynucleotide. An RNA strand that functions in this capacity is called a primer. Primers are formed at points along the chromosome they base-pair with the single-stranded template DNA in the regions where they are formed. 

Designing the target-specific primer (primer-3) in such a way that its 3 end has the target-specific sequence and the 5 end has a part of the omega sequence. 

Primers. Primers tend to hinder adhesive strength degradation in moist environments by providing corrosion protection to the adherend surface. A fluid primer that easily wets the interface presumably tends to fill in minor discontinuities on the surface. Qrganosilane, organotitanate, and phenolic primers have been found to improve the bond strength of many adhesive systems. 

Figure 2. Allele specific determination of single nucleotide polymorphisms (SNPs). (a) The determined SNP responsible for resistance is flanked by either allele specific primes (primer pair 1 and 3 or 1 and 4, respectively) or by species specific primers (primer pairs 1 and 2). (b) The allele specific (top) or species specific (below) amplified fiagments are examined by different methods (c) yes/no answer on an agarose gel stained with ethidiiun-bromide, or with fiagments were measured in real time PCR equipment using different chemistries imiversal dye Sybr Green, fiagment specific probes (top) or allele specific probes (below).

The use of primers is also advisable if the bonded parts are to be subjected to temperature changes, damp conditions, tension compression, shear forces, etc. Some porous substrates and plastic materials also require primers. Primers can be applied to a thoroughly prepared surface by brushing, spraying or dipping to form a thin film. All primers contain flammable solvents and therefore safety precautions are essential.

The specificity of PCR derives from the primers. Primers are short pieces of single-stranded DNA that are the starting point of the new DNA strands. The primers recognize the target DNA segment in the sample and... 

The PCR products purified by agarose gel electrophoresis were used as template DNA for the second stage-overlapping PCR without primers. In this process, strands having the same base pairs (20 bases) overlapped and acted as primers for each other. In the third PCR, the combined fragment (chimeric enzyme gene) was amplified using forward and reverse primers (primers 1 and 4). 

PGR with M-BCR-b2 and ABL-a2 primers (primers 1 and 4) generates a 111-bp DNA fragment (b2a2 transcript). 

PCR with ABL-a2 and ABL-a3 primers (primers 5 and 6) used as an internal control. 

J Y J12 consensus primer to J1 and J 2 regions JyJp2 consensus primer to J p 1 and Jp 2. PGR carried out in two reactions, first reaction using both V forward primers (primer 1 and 2) with one J reverse primer (primer 3). This reaction generates a band on electrophoreses 75-95 bp in size, second reaction using the same V forward primers with the other J reverse primer (primer 4). This reaction generates a monoclonal band (or two bands) on electrophoreses 80-110 bp in size.
