WebMay 20, 2024 · When screening for stable integrations, transgenes that express fluorescent proteins (e.g. GFP) are easy to detect, but other transgenes are not. The Tol2kit uses site-specific recombination-based cloning ( multisite Gateway technology) to allow quick, modular assembly of promoter-coding sequence-3' tag constructs in a Tol2 transposon … WebFor PCR amplification using such long primer (Gateway primers) , generally use tm of actual primer excluding attB1/B2. if in such case tm is below 52 or gene is not being amplified …
WebThe Gateway attB sites are derived from the bacteriophage lambda site-specific recombination, but are modified to remove stop codons and reduce secondary structure. The core regions have also been modified for specificity (i.e., attB1 will recombine with attP1 but not with attP2). The first step in Gateway cloning is the preparation of a Gateway Entry clone. There are a few different ways to made entry clone. 1. Gateway attB1 and attB2 sequences are added to the 5' and 3' end of a gene fragment, respectively, using gene-specific PCR primers and PCR amplification. The PCR amplification products are then mixed with a proprietary mixture of plasmids called Gateway "Donor vectors" …
