t-Boc-N-Amido-PEG8-propargyl has an alkyne group and Boc-protected amine. The alkyne group reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The deprotection of Boc-protected amine can be peformed under mild acidic conditions. The hydrophilic PEG chain enhances the solubility of the molecule in aqueous solution. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Principle
The MagSelect method contains magnetic particles in an optimized binding buffer to selectively bind DNA fragments 100bp and larger to paramagnetic beads. Excessprimers, nucleotides, salts, and enzymes can be removed using a simple washing procedure. The result is a more purified PCR product.
Advantages
High recovery – up to 80%
High throughput – using magnetic beads purification technology

Storage and Stability
MagSelect XP should be stored at 2-8°C upon arrival and is stable up to 18 months under the condition. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect its performance. Shake the reagent well before use. It should appear homogenous and consistent in color.
DO NOT FREEZE.

For the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017.
Principle and Interpretation
Meat extract and casein provide a source of nitrogen and amino acids and sodium chloride maintain theosmotic balance. Ox bile and brilliant green act as selective agents against non-target microorganisms. Tetrathionate is generated from the sodium thiosulfate. Iodine and calcium carbonate buffer the sulfuric acid generated from tetrathionate reduction.
