t-Boc-aminooxy-PEG4-propargyl is a click chemistry tool containing a propargyl group and t-Boc-aminooxy group. Propargyl group is reactive with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to yield a stable triazole linkage. T-Boc-aminooxy can be deprotected under mild acidic conditions and then can react with an aldehyde or ketone group to form a linkage. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Novel method
The β-Glucan Assay Kit (Yeast and Mushroom) is suitable for the indirect measurement of 1,3:1,6-β-glucan in yeast and mushroom preparations containing starch, glycogen, sucrose and trehalose.
We are happy to announce a new and improved procedure!
Trehalase enzyme has now been added to the β-Glucan Assay Kit (Yeast and Mushroom), further increasing the accuracy of β-glucan measurement for certain samples. The addition of trehalase removes instances of overestimation of β-glucan content in samples containing trehalose. Please refer to the assay protocol and the FAQ here for more information.
This product replaces the Enzymatic Yeast β-Glucan Assay Kit (K-EBHLG) as the method of measurement for β-glucan measurement in yeast samples. See here for more information.
All reagents stable for > 12 months after preparation

How to use： 1.Suspend 38g in 1 L of distilled water , stirring heated to boiling until completely dissolved, dispensing flask, 121 ℃ autoclave for 15min. 2.Diluted and treated samples.
Storage: Keep container tightly closed, store in a cool, dry place, away from bright light. Storage period of 3 years.
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.
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.
