DBCO-PEG24-TFP ester is a heterobifunctional PEG linker with an azide-reactive DBCO and an amine-reactive TFP ester that is less susceptible to hydrolysis than an NHS ester. The PEG linker improves the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

CDX-2 is a caudal-related homeobox transcription factor that is expressed by intestinal epithelial cells. CDX-2 is a useful marker for gastrointestinal carcinoma, and for determining the origin of gastrointestinal metastatic adenocarcinoma and carcinoids. Anti-CDX-2 is used for differentiating lung and metastatic colorectal adenocarcinoma, however mucinous ovarian carcinoma also react positively with Anti-CDX-2, thereby limiting the ability to differentiate from metastatic colorectal adenocarcinoma.
HiPure FFPE Nucleic acid Kit supplies a simple and rapid DNA extraction for formalin-fixed, paraffin-embedded (FFPE) tissue and sections samples. This kit is based on silica gel column purification technology, no phenol-chloroform extraction or alcohol precipitation. The whole extraction only takes 20 minutes (not including digestion time). DNA can be directly used for downstream applications such as PCR, southern blot and viral DNA detection, etc.

Hipure FFPE Nuclear acid kit adopts silica gel column purification. The sample is deparaffinated by xylene and digested by lysate and protease. After de crosslinked at 90 ℃, DNA/RNA is released into the lysate. Adding ethanol to adjust the binding conditions, the sample is transferred to the column where DNA/RNA is adsorbed on the membrane and protein is removed without adsorption. Protein and other impurities are washed by buffer GW1, and the salt is removed by buffer GW2. Finally, the DNA / RNA is eluted by low salt buffer.

Storage and Stability
Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
Experiment Data
HiPure FFPE Nucleic acid Kit supplies a simple and rapid DNA extraction for formalin-fixed, paraffin-embedded (FFPE) tissue and sections samples. This kit is based on silica gel column purification technology, no phenol-chloroform extraction or alcohol precipitation. The whole extraction only takes 20 minutes (not including digestion time). DNA can be directly used for downstream applications such as PCR, southern blot and viral DNA detection, etc.
This kit enables the rapid purification of amplified DNA products from PCR mixes. It is able to effectively remove PCR by-products including primers, dimers, enzymes, unincorporated nucleotides and mineral oil from the desired PCR product. The purified PCR products are fully compatible with restriction enzyme digestion, ligation into vectors, labeling, sequencing and more. This kit can also be used as an alternative to organic extraction and ethanol precipitation to clean up various enzymatic reactions.
The kit is also available in a 96-well format for high-throughput PCR purification. Purification with the 96-well plate can be performed using either a vacuum manifold or centrifugation.
