TIGIT is an immune receptor present on some T cells and Natural Killer cells. TIGIT binds with high affinity to the poliovirus receptor (PVR) which causes increased secretion of IL10 and decreased secretion of IL12B and suppresses T cell activation by promoting the generation of mature immunoregulatory dendritic cells. Through the CD226/TIGIT-PVR pathway, TIGIT regulates T cell mediated immunity. In cancer, TIGIT and PD-1 have been shown to be over-expressed on tumor antigen-specific CD8+ T cells and CD8+ tumor infiltrating lymphocytes (TILs) from individuals with melanoma. Blockade of TIGIT and PD-1 led to increased cell proliferation, cytokine production, and degranulation of tumour antigen-specific CD8+ T cells and TIL CD8+ T cells. It can be considered an immune checkpoint.
DBCO-PEG5-TFP Ester is an amine-reactive, labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers. The hydrophilic polyethylene glycol (PEG) spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules.

Storage and Stability
MagPure RNA Particles should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect its performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

Norgen’s Saliva DNA Isolation Kit (Magnetic Bead System) provides a fast and reproducible method for isolating genomic DNA from saliva samples collected and preserved using Norgen’s Saliva DNA Collection and Preservation Devices, as well as fresh saliva. Saliva DNA purified using Norgen’s kit is of the highest quality, and is compatible with a number of downstream research applications including PCR, Southern Blot analysis, sequencing and microarray analysis.
Norgen’s Saliva DNA Isolation Kit (Magnetic Bead System) is also available in a 96-well format for high throughput applications. Purification with the 96-well plates can be integrated with a robotic automation system.

Storage Conditions and Product Stability
The kit contains ready-to-use Proteinase K which is dissolved in a specially prepared storage buffer. The Proteinase K should be stored at room temperature or 4°C. All other solutions should be kept tightly sealed and stored at room temperature (15 – 25°C). These reagents should remain stable for at least 2 years in their unopened containers.
