GC 2x master mixes are ready-to-use mixes based on either GC Buffer I or GC Buffer II. GC TEMPase master mixes are specifically developed for the amplification of GC-rich DNA sequences.
FEATURES
High success rate with amplification of GC-rich DNA
High sensitivity, specificity and product yield
Diminished formation of non-specific products
Reaction set-up at room temperature
DESCRIPTION
GC-rich 2x master mixes consist of TEMPase Hot Start DNA Polymerase combined with either GC Buffer I or GC Buffer II, dNTPs and MgCl2. Just add DNA template and primers to successfully carry out PCR.
4x GC Buffer I and II are also available separately.
TIP - WHEN TO CHOOSE SPECIALISED GC BUFFERS
If your PCR fails with TEMPase Hot Start Polymerase in combination with Ammonium Buffer, we kindly recommend you to try TEMPase in combination with GC Buffer I either as master mix or GC-rich DNA Target Kit. If your amplification is still not satisfactory, then switch to GC Buffer II. To save time both GC buffers can be tested at the same time.
OPTIMISATION OF GC-RICH DNA AMPLIFICATION
Six genes with varying percentage of GC contents were amplified with Standard Buffer (lanes S), Ammonium Buffer (lanes A), GC Buffer I (lanes I) and GC Buffer II (lanes II). M. Marker. With an increasing percentage of GC content in the expected amplicon, Standard Buffer and Ammonium Buffer fail to support the correct amplification products, while GC Buffer I and GC Buffer II succeed. Correct amplified products are encircled.
COVERAGE STUDY OF GC TEMPASE MASTER MIX I
GC TEMPase I displays superior performance on a broad range of amplicons with a GC content ranging from 41 – 78 %. Five genes with increasing percentage of GC content were amplified using GC TEMPase Master Mix I. Lane M is Marker (Iqon DNA Mini Ladder). Number of PCR cycles used in this study is 40.
