Forward primers

AP = adaptor primer FP = forward primer RP = reverse primer... 

The design of the internal primers for generation of a deletion mutation is also similar to that for a point mutation. The two primers are complementary to one another and consist of a region on each end that is complementary to the template with the deletion mutation at the center. In other words, the 5 half of the forward primer is identical to the sequence of the template found upstream of the 5 end of the desired deletion. The 3 half is identical to the sequence found downstream of the 3 end of the desired deletion. The primers are designed to flank the deletion, generally 15 bp before tbe deletion point and then the 100-200 bp deletion followed by the 5 terminal 15-bp primer. 

PCR screen colonies or plasmid minipreps as usual with a vector-specific (e.g. T7) forward primer and your gene-specific reverse primer. 

Primer region 1 (P-40, 40 bp, forward primer with T7 promoter site)... 

The purified DNAs are used as templates for in vitro transcription reactions. Forward primer (P-40, same sequence as primer used during SELEX process) and reverse primer (p-22 pGEM). 

The PCR is a three-step cyclic process that repeatedly duplicates a specific DNA sequence, contained between two oligonucleotide sequences called primers (154,155). The two primers form the ends of the sequence of DNA to be amplified and are normally referred to as the forward and reverse primers. The forward primer is complementary to the sense strand of the DNA template and is extended 5 to 3 along the DNA by DNA polymerase enzyme (Fig. 27). The reverse primer is complementary to the antisense strand of the DNA template and is normally situated 200-500 base pairs downstream from the forward primer, although much longer sequences (up to 50 kbase) can now be amplified by PCR. The process employs a thermostable DNA polymerase enzyme (such as the Taq polymerase from Thermus aqualicus BM) extracted from bacteria found in hot water sources, such as thermal pools or deep-water vents. These enzymes are not destroyed by repeated incubation at 94 °C, the temperature at which all double stranded DNA denatures or melts to its two separate strands (155). 

Amplify genes of interest using a high-fidelity polymerase (such as Platinum Pfx polymerase) with primers that contain 5 extensions for LIC. For the pNHis vector, the forward primer uses the extension 5 GGTATTGAGGGTCGC, followed by the cDNA sequence starting with the second codon. The reverse primer uses the extension 5 AGAGGAGAGTTAGAGCCTTA. Note that a stop codon is added to this sequence so that the product does not contain additional amino acids encoded by the LIC sequence (see Note 4). 

Forty-eight variants of p53 were generated by inverse PCR using the wild-type p53 expression vector, pQE-80L H6-BCCP-p53, as template. Phosphory-lated forward primers bore the sequence variation at the 5 -terminus followed by 20-24 nucleotides ofp53 sequence. Unphosphorylated reverse primers were...

Rintamaki et al. (2002) performed heterogeneous hybridization assays to detect Streptococcus pneumoniae DNA using an Eu3+-labeled probe (table 5). The procedure is as follows Firstly, usual PCR is performed for S. pneumoniae DNA using a forward primer labeled with... 

Position numbers are relative to the Escherichia coli 16S rDNA nucleotide sequence. The forward primer mollil and the reverse primer molli2a are used to detect Mycoplasma species. The forward primer mollil and the reverse primer molli2b are used to detect Acholeplasma species. Each set of primers are used separately. 

Screen the recombinant clones by sequencing with reverse and forward primers as described in Subheading 3.7. to verify the presence of the viral sequences. 

Fig. 14. Using Tag prob e arrays to screen protein activity. To a protein-encoding mRNA a 5 tag sequence and a 3 ribosome-biocking sequence are attached (A). In a pool of such molecules, such as a randomly mutated gene library, each mRNA is paired with a imique tag and all have the same 3 sequence. Following in-vitro translation either on a microarray or in a test tube, the nascent protein remains attached to the mRNA (B). During hybridization the tag directs each mRNA-protein to a particular address on the Tag probe array (C), where all the proteins are screened simultaneously for activity (D). Appropriate detection methods identify proteins of interest (E, black and/or shaded blocks). Finally, the corresponding genes can be captured by PCR of the mRNA pool using a imiversal reverse primer and each identified Tag sequence as a forward primer...

Fig. 2. Alignment view of one of the primer hits to the GenBank entry L78833.1. The forward primer (query nucleotides 1. .19) aligns to the sequence L78833.1 on the forward strand (indicated by Strand Plus/Plus) at nucleotides 3252..3270. The reverse primer (query nucleotides 56..74) aligns to the reverse strand (indicated by Strand Plus/Minus) at nucleotides 3475.3457. The Strand information is highlighted by rectangles and the nucleotide locations of L78833.1 are highlighted by ovals.
