PCR PRODUCT CLONING AND SEQUENCING

For positive-selection cloning of PCR products through blunt-end ligation. Allows direct cloning of PCR products without purification.
This system uses a third generation cloning vector that features positive selection for cloning PCR products. Only recombinant plasmids confer antibiotic resistance, making PCR-TRAP extremely efficient. There is no need for any post-PCR manipulation before cloning, since a significant fraction of PCR products do not contain the 3' overhanging A (Clark, 1988, Nucleic Acids Res. 16:9677) The mechanism of this unique cloning system involves the phage Lambda repressor gene, cI, which has been incorporated into the PCR-TRAP Vector. When transcribed, the gene codes for a repressor protein which binds to the Lambda right operators Or1 to Or3 of the cro gene, turning off the promoter which drives the TetR gene on the plasmid. Therefore, cloning the PCR product directly into the cI gene leads to the inactivation of the repressor gene and thus the expression of the TetR gene. So the PCR-TRAP Cloning System is indeed a cloning TRAP! request info

This kit contains some of the essentail components of the PCR-TRAP Cloning System. Other components such as T4 DNA ligase, Component cells, and Tetracycline are not provided. request info

For PCR amplification of cDNAs cloned into the PCR-TRAP® system for riboprobe preparation.

For labeling cDNA probes for use in "Reverse Northern" blots.
ReversePrime Kit provides a complete system for labeling cDNA for use in "Reverse Northern" blots to conduct differential screening of positive clones generated by differential display. This kit is ideal for either dot blot or colony hybridization screening of differential display PCR products cloned into the PCR-TRAP® Cloning System. request info

For optimized labeling of differential display fragments with radioactively labeled dATP.
The HotPrime DNA labeling kit features three unique improvements over the traditional "random priming" method which allow for radioactive labeling of DNA probes with at least 5-10X more specific radioactivity. It is designed to efficiently label cDNA probes isolated from differential display for Northern or Southern blot analysis as well as library screening. However, the HotPrime Kit can also label DNA probes for any other application to a similar high specific activity. request info

AP-TAG PRODUCTS

For non-radioactive detection of receptor/ligand interaction.

AP-TAG Kit A
This is the second generation of AP-TAG technology. A secreted ligand or soluble receptor can be fused with secreted alkaline phosphatase (AP) at either its N- or C-terminus to produce an "AP-body". The resulting AP fusion protein can be expressed as a secreted protein and used directly as highly sensitive affinity agents much like an antibody. request info

AP-TAG Kit B
This single vector system is the third generation AP-TAG technology. A secreted ligand or soluble receptor can be fused with secreted alkaline phosphatase (AP) at either its N- or C-terminus to produce an "AP-body". The resulting AP fusion protein can be expressed as a secreted protein and used directly as highly sensitive affinity agents much like an antibody. The epitope tags (6xHis and myc) allow easy purification, detection and interaction assays (IP) of the AP-fusion proteins. request info

For Transformation of AP-TAG Cloning Vectors.

GH2/P3 Supercompetent Cells
For transformation of pAPtag-2 and pAPtag-4 vectors.
The pAPtag-2 and pAPtag-4 AP-fusion cloning vectors contain the supF gene which confers both ampicillin and tetracycline resistance when transformed into the GH2/P3 Supercompetent Cells. pAPtag-2 and pAPtag-4 vectors will not confer antibiotic resistance in an E. coli host which does not contain the P3 episome. request info
