ExAssist Helper Phage w/ XOLR

The ExAssist helper phage with XOLR works with the Lambda expression vector system kits for mass excision of libraries in ZAP Express or Lambda ZAP vectors. The pCMV-Script or pBluescript phagemid will grow.

The ExAssist helper phage is designed to allow efficient in vivo excision of the pBK-CMV phagemid vector from the ZAP Express vector while preventing problems with helper phage co-infection. The ExAssist helper phage allows simple and rapid excision of multiple clones. Excision efficiency is monitored at the clonal level.

Features:

• ExAssist contains an amber mutation that prevents replication of the phage genome in a nonsuppressing E. coli strain (e.g., XLOLR cells)
• XLOLR cells are resistant to Lambda infection prevent lambda DNA contamination after excision
• XLOLR cells are resistant to Lambda infection prevent lambda DNA contamination after excision
