DBCO-NHCO-PEG5-NHS ester is a PEG linker containing NHS ester that is able to react specifically and efficiently with primary amines such as the side chain of lysine residues or aminosilane-coated surfaces at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and can also provide a long and flexible connection that minimizes steric hindrance during ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Attogene Fluorescent UniversalLateral Flow Assay Kits are a convenient ready-to-use kit for quick and cost-effective development of a fluorescent lateral flow dipstick assay for detection of DNA and RNA products.
Fluorescent lateral flow assays can be 2-100 fold more sensitive that gold based lateral flow tests.
Formats (fluorescent broad range UV light excitation range of 100nm to 400nm, 655nm emission) Streptavidin conjugate pad):
• Detectable using a black light such as a black light UV flashlight or fluorescent lateral flow reader.
• Detection of nucleic Acid (DNA or RNA) requires the use of a biotin and FAM-labelled primer during amplification.
• Test line: anti-FITC/FAM
• Control Line: Biotin
• Multiplex detection of nucleic Acid (DNA or RNA) requires the use of a biotin, FAM and Dig labelled primers during amplification.:
• Test Line #1: anti FITC/FAM, Line #2: anti-Dig, Line #3 Biotin.
