Enjeksiyon için DNA
Enjeksiyon için Plazmid DNA çözüm EndoFree plazmid kiti kullanılarak izole edilmiştir. Construct ve doğru konsantrasyon birlikte Yardımcısı plazmid karışımı, izopropanol hızlandırdı. Pelet enjeksiyon tampon resuspending önce% 70 etanol ile yıkandı. Enjeksiyon, önce Millex-GV sütun kullanarak temiz DNA.
