DBCO-TFP ester

Description

Biotin is extensively used in combination with streptavidin in biological assays.  Our biotin detection kits have multiple applications in detecting biotin attachment and efficiency of conjugation during biotinylation processes.  These kits are perfect for understanding the efficiency of the reaction and free biotin in your solutions that can interfear with Streptavidin-biotin interactions.

Attogene offers three kits to detect and quantify biotin using three different technologies including Lateral Flow, ELISA and Chemical.  these kits are accurate and sensitive compared with common instrumental analysis.

Can be used to calculate the amount of biotin in liquid samples including biological samples including biotinylated antibody, free biotin in solution, foods, plasma and serum as needed.  Also, can be used to quantify the % biotinylation following standard biotinylation reactions.

The ChIP-Seq Library Prep Kit (illumina and MGI Platform) was developed for the construction of high quality ChIP-Seq libraries using 5 ng to 400 ng of ChIP DNA as input. The kit is compatible with ChIP DNA fragments generated from both enzymatic methods and physical methods (sonication, nebulization etc.).

ChIP-Seq Library Prep Kit Workflow

ChIP-Seq is the combination of chromatin immunoprecipitation (ChIP) with next generation sequencing. It is a powerful tool for the analysis of global transcription factors and other proteins in diseases and biological pathways, and characterization of histone modifications in a genome-wide level at single-base resolution. ChIP-Seq delivers whole genome level of functional profiling of global transcription factors, and provides better understanding of epigenetic modifications.

Three index types are available for the ChIP-Seq Library Prep Kit of the illumina platform:

Non-index (Cat.# 30032): Libraries do not have index.

Index (Cat.# 30034): Each index primer contains a unique 6-base index sequence can be used for identification. 48 samples can be pooled together. Index information can be downloaded here.

Unique dual index (Cat.# 30036): The ChIP-Seq library multiplexing for 96 samples is possible. Our unique 4-Base Difference Index System have 8 bases index length and at least 4 bases are different from each other for better library identification. Our unique dual indexing primers remove sequencing errors such as index hopping, index contamination, mis-assignment, and other errors. Index information can be downloaded here.

Indexes are available for the MGI platform kits (Cat.# 34034).

Kit advantages:

• Super fast protocol
  • Library prep can be done in 1.5 hours
  • The hands-on time is only around 10 minutes
• Easy procedure
  • Ready-to-use master mix simplified the procedure
  • Less reaction components make it easy to setup reactions
• Reduced more than half of the beads cost
• Input ChIP DNA: From 5 ng to 400 ng

Water-soluble, substrate for sortase mediated labeling of proteins. Sortase catalyzes a transpeptidase reaction between a specific internal sequence of a protein and an amine group present on the N-terminus of triglycine recently has become an area of great interest. This method of labeling proteins has been denoted as “Sortagging”. Proteins conjugated to DBCO-Gly-Gly-Gly can be further modified with azide-containing molecules creating site-specific protein conjugates. Examples of creating protein conjugates using sortagging include site-specifically PEGylating proteins,1 site-specific protein-lipid conjugates,2 and constructing peptides and glycosylphosphatidylinositol chimeras.3 Sortase has also been used in peptide synthesis to cyclize peptides to create macrocyclic peptides, glycopeptides4 and protein−protein conjugates.
