GeneAb™ SALL4

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.

Description

Attogene Fluorescent Universal Lateral 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.  Europium dyed polystyrene beads conjugated to streptavidin

Formats (fluorescent broad range UV light excitation range of 300nm to 400nm, 610nm 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.

Inquire about custom configurations: [email protected]. 

For example, this product can be configured with alternative/custom streptavidin fluorescent particles.

• Non-invasive, user-friendly sample collection
• Suitable for self-collection of saliva samples supervised by a trained individual in the collection procedure by watching the training video and reading over the collection instructions.

Norgen’s Saliva RNA Collection and Preservation Devices Dx are designed for 1) safe and non-invasive supervised self-collection of saliva specimens and 2) preservation of RNA in saliva specimens at ambient temperature. Each of the 50 Saliva RNA Collection and Preservation Devices Dx consists of 3 components: (1) Saliva Collection Funnel and Collection Tube, (2) Collection Tube Cap, and (3) Norgen’s Saliva RNA Preservative contained within a sealed squeezable ampoule. Saliva collection is performed through supervised self-collection. Saliva samples are collected by spitting inside the Collection Funnel which has been assembled with the Collection Tube. After collecting the required volume of saliva the Collection Funnel is removed and the contents of the Preservative Ampoule are then added and mixed with the collected saliva. The Saliva Collection Tube is subsequently sent to the laboratory for RNA isolation and analysis. RNA can be isolated from the preserved saliva samples using Norgen’s Saliva/Swab RNA Purification Kits Dx (Cat# Dx69100, Dx69300). Each of Norgen’s Collection Tubes is labeled with a unique serial number that can be used for secure and anonymous tracking of the sample. The saliva RNA in preserved samples is stable for up to 2 months at room temperature. This kit is ideal for collecting and preserving RNA samples for in vitro diagnostic use for medical purposes. This kit can be used to collect and preserve viral RNA, including SARs-CoV-2 RNA for detection of COVID-19.

Norgen’s Saliva RNA Collection and Preservation Devices Dx do not provide a diagnostic result. It is the sole responsibility of the user to use and validate these devices in conjunction with a downstream in vitro diagnostic assay.

Saliva RNA Preservative

Norgen’s Saliva RNA Preservative is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of RNA from fresh saliva specimens. The buffer eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperature. The components of the buffer allow samples to be stored for up to 2 months at room temperature. The Saliva RNA Preservative also inactivates all bacteria, yeast and viruses present in the saliva sample.

Nucleic Acid Isolation from Preservative

Saliva RNA can be isolated from the preserved saliva samples using Norgen’s Saliva/Swab RNA Purification Kits Dx (Cat# Dx69100, Dx69300). To minimize irregularities in diagnostic results, suitable controls for downstream applications should be used.

Shelf Life and Handling

• The Collection Device should be kept tightly sealed and stored at room temperature for up to 2 years without any reduction in kit performance (The collection due date is written on the device label).
• Once collected, saliva RNA is stable for up to 2 months when kept tightly sealed and stored at room temperature.
• The Collection Tube, the Collection Funnel and the Device Container of each individual Saliva RNA Collection and Preservation Device are recyclable.
