Description 

Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Laemmli Tris-HCl gels. 

Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) concentrations of polyacrylamide in 12-and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems. 

Key Features

• User-friendly gel cassette:
  • Numbered and framed wells for sample loading
  • Labeled warning sign and green tape as reminder
• Enhanced gel performance: 
  • Enhanced band sharpness
  • Better resolution of small proteins 
  • Stable for shipping at ambient temperature
• Easy compatibility: 
  • Available as homogeneous and adjusted gradient gels for a wide range of protein separation.
  • Compatible with most popular protein electrophoresis systems 

Storage and stability

Store Q-PAGE™ Precast Gels at 4°C for periods up to 12 months.

Do not freeze Q-PAGE™ Precast Gels. Remove tape and comb before electrophoresis. 

Keep Q-PAGE™ Precast Gels flat during storage.

The Bisulfite Sequencing Library Prep Kit (illumina platform) was developed for construction of NGS libraries using bisulfite treated DNA (50 ng – 500 ng) as input. DNA methylation is an epigenetic mechanism known to play a critical role in gene regulation and genomic imprinting by blocking transcription factor access to promoters and enhancers. Bisulfite sequencing is a popular technique in biomedical research based on C to T conversion under the treatment of sodium bisulfite.

Recently, NGS became a powerful tool to identify the DNA methylation status at the whole genome level with single-base resolution. However, it is well known that bisulfite treatment of the NGS libraries causes tremendous damage to the libraries.

Bisulfite-Seq kit comparison

In the case of the regular bisulfite seq library preparation (library prep before bisulfite conversion), the DNA shearing equipment and the expensive methylated adaptors are required. In addition, the subsequent bisulfite conversion causes tremendous DNA damage to the constructed libraries.

BioDynami has developed a unique library prep technology to solve the problems. The technology uses bisulfite treated DNA as input to avoid the significant library loss caused by bisulfite conversion. Furthermore, DNA shearing step and expensive methylated adaptors are not required with our kit. The DNA polymerase in the kit has high-fidelity amplification ability and uracil tolerance which is ideal for amplification of bisulfite sequencing libraries. The final library is strand specific.

Bisulfite Sequencing Library Prep Kit Workflow

Three index types are available for the kit:

Non-index (Cat.# 30091): Libraries do not have index.

Index (Cat.# 30092): Each primer contains a unique barcode sequence of 6 bases to identify the individual library. Library multiplexing capacity is up to 48 samples. Index information can be downloaded here.

Unique dual index (Cat.# 30093): The multiplexing of bisulfite sequencing library is up to 96 samples with unique dual indexes. We used a Four-Base Difference Index System to generate indexes that have at least 4 bases different from each other in the 8-base index. The index primers remove NGS errors including index cross-contamination, index hopping, reads mis-assignment etc. Index information can be downloaded here.
