Details

SiliaBond® Triethylamine (SiliaBond WAX-2) is a silica bound tertiary amine base and can be used in most applications requiring a tertiary amine, particularly as a HCl sponge. Silica bound ammonium salt by-products are easily separated by filtration. This triethylamine immobilized on silica gel can be used for the same applications as SiliaBond Dimethylamine. It is a very common supported tertiary amine.

SiliaBond Triethylamine is also used as weak anion exchanger (WAX) in SPE. It has a pka of ≈10.5 and is preferred over SiliaBond TMA Chloride (SAX) when performing “Catch and Release” purification of compounds bearing a permanent negative charge such as salts of sulfonic acids. Using SAX in this case could make the release of the compounds of interest difficult, not to say irreversible, due to the strong interaction between the two strong ions.

Details

SiliaPrep Triethylamine (WAX-2) is a weak anion exchanger that can be used in replacement of SAX and SAX-2 for strong anions to avoid irreversible retention. This phase presents a slightly lower capacity and a moderate non polar character due to the alkyl chain on the amino function. Moreover, it can be employed as metal scavenger and in normal phase conditions.

生物活性

Cy5-SE (Cy5 NHS Ester) triethylamine salt is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides. Cy5-SE triethylamine salt is ideal for very cost-efficient labeling of soluble proteins, as well as all kinds of peptides and oligonucleotides Ex=649 nm; Em=670 nm)[1].

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Conjugation of SELP Analogues with Cy5-SE.
1. 1 mL of each 100 μg/mL SELP solution in 100 mM sodium bicarbonate buffer (pH 8.3) is mixed with 10 μL of 1.2 mg/mL Cy5 mono NHS-ester in 10% DMSO and incubates for 2 hours on ice.
2. To quench the reaction, 50 μL of 1 M Tris-HCl (pH 8.0) is added to the reaction solution.
3. Reaction mixtures are loaded onto 1.5 mL Sephadex G-25 columns, and Cy5-conjugated SELPs are eluted by centrifugation for 3 minutes at 1050g[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
