Product Info
Aminooxy-PEG4-propargyl is a aldehyde reactive crosslinker. The aminooxy group reacts with an aldehyde or ketone group to form a stable oxime linkage. The propargyl group is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

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.

Description
The ExcelRT™ Reverse Transcriptase is a recombinant Moloney Murine Leukemia Virus (M-MLV) reverse transcriptase – an RNA dependent DNA polymerase capable of generating first strand cDNA using an RNA template. It is designed to reduce RNase H activity and create better thermal stability. The ExcelRT™ Reverse Transcriptase is able to routinely synthesize first strand cDNA >8 kb at 37~50°C.
Features
High yield
Thermostable, up to 50°C, during first strand synthesis
High processivity, generating cDNA up to 8 kb
Reduced RNase H ribonuclease activity
Application
Generation of first strand cDNA from total RNA or mRNA.
Suitable for generating cDNA from RNA with strong secondary structure which can be reduced at temperature up to 50°C.
