R408 Helper Phage DNA 10 µg P2341 138.00
For Research Use Only. Not for Use in Diagnostic Procedures.
Description: The pGEM ® -Zf Vectors require the presence of a helper phage
in order to be propagated, packaged and secreted as single-stranded DNA
(ssDNA) viral particles. R408 helper phage allows the preferential secretion
of single-stranded plasmid DNA over the phage ssDNA, thereby increasing
the absolute yield of plasmid ssDNA. Differences in the yields and absolute
amounts of plasmid and phage ssDNA produced have been observed to be
dependent on the particular host and vector combination.
Concentration: Minimum specification is ≥5 × 10 10 pfu/ml.
Features:
• Increased Single-Stranded DNA Yield: R408 Helper Phage allows
the preferential secretion of single-stranded plasmid DNA over the phage
ssDNA.
Storage Conditions: Store at –20°C.
