Propargyl-PEG7-acid is a reagent with a propargyl group with a carboxylic acid. The carboxylic acid reacts with primary amines under the activation of EDC or HATU. The propargyl group can participate in azide-alkyne Click Chemistry reaction to form triazole linkage, copper is required as a catalyst. The PEG spacer increases the hydrophilicity of the molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The 23S ribosomal RNA (rRNA) is a crucial component of the bacterial/archean ribosome. The 23S rRNA is a 2,904-nucleotide long component of the large subunit (50S) of the ribosome. Compared to 16S rRNA genes, 23S rRNA genes have greater sequence variations due to unique insertions, deletions, and length. Attogene’s 23s PCR kit is designed for identification of specific strains of bacterial/archean using the ribosomal RNA gene region for use in Phylogenetic studies of bacterial diversity from environmental DNA samples such as water. For example, a sample of algae is obtained and washed to extract a clean algal genomic DNA (gDNA) sample. A reaction mixture is assembled from primers, master mix, and gDNA samples as required. The qPCR machine of choice is set up and loaded as needed and the mixture undergoes PCR amplification. The Primer mix provided exploits the Taq polymerase to amplify the gene region of interest.
This kit is sufficient for 150 reactions:
For characterizing cyanobacteria in environmental samples
Use in combination with Attogene Algae DNA isolation kit
Universal 23s PCR primers
Perfect for Environmental DNA (eDNA) Characterization
Attogene’s Human IgG/IgM universal fluorescent lateral flow assay kit is a ready-to-use, universal test strip, which is based on the lateral flow technology that uses 655nm Emission Quantum Dot particles containing streptavidin to conveniently capture biotinylated antigens. The device is designed to easily develop qualitative or quantitative rapid test systems for detection of anti-human IgG and IgM antibody that react to the any antigen that can be biotinylated (i.e. viral antigen, autoimmune antigen) and is easily customizable providing every laboratory with the possibility to perform assay feasibility.
Formats (fluorescent broad range UV light excitation range of 300nm to 400nm, 610nm emission) Streptavidin conjugate pad):
Antibody tests are a method of choice to determine if a person has been exposed to a pathogen or not. They are also incredibly valuable in the detection of autoantibodies that can be found in human autoimmune disorders. In this test, a biotinylated antigen (User supplied) is mixed with a biotinylated rabbit IgG (bind to goat anti rabbit control line) and sample (human sera or plasma) is simply mixed into with the specially designed assay running buffer in a well of the supplied 96-well plate, mixed and is then added to the sample port of the cassette. Generally, the reaction is complete in 10-15 minutes. It is very important to note that the relative stoichiometry between the biotinylated antigen, biotinylated rabbit IgG added, and the streptavidin gold is critical for assay optimization. The appropriate concentration of biotinylated antigen to use with strips is dependent upon the purity and sequence and a standard curve can be used to determine the relative ratio (generally between 1ng-100ng per test). A positive control line (biotin-rabbit IgG) antibody will bind to the goat anti rabbit (GAR) line on the test to ensure the assay is running appropriately.
