Experimental status of 1279B

Note: Dates prior to 10/24/01 may be inaccurate, due to conversion from a record-keeping system which tracked only the last experimental date, to a new system which keeps track of all dates. The user is the person who entered the data, not the person who did the experiment. This will also change in the future.

1279B Potential Cloning Problems

No UGA codons or (bad) restriction sites!

Back to Top


1279B Automatically Selected Primers

Note: These were generated using Hisao's algorithm, and do not take into account possible mispriming, self-complementarity, or requirements for mutations anywhere in the sequences. The -R1 primers are for the N-terminal end, and begin with an NdeI restriction site (CATATG). The -R2 primers are for the C-terminal end, and begin with a BamHI site (GGATCC) if the target has no other BamHI sites. If the target does have a BamHI site, the -R2 primer wil begin with a BglII site (AGATCT), unless the target has no BglII sites. If the target has both sites, the design program gives up and doesn't prepend a restriction site to the -R2 primer!

Predicted Tm was obtained using the Tm determination tool at the Virtual Genome Center.
