Isopeptidase-Fluorogenic
Assays

Art. No.

A101

Background info

Also suitable for TG1, TG2, TG3 and TG6

Molecular Formula

C₈₀H₁₂₃F₃N₂₀O₂₇ (free base: C₇₈H₁₂₂N₂₀O₂₅)

Molecular Weight

1853.95 (free base: 1739.92)

Purity by HPLC

>95 % (HPLC)

Appearance

yellow solid

Solubility

50 μM in 0.1% (v/v) DMSO / aqueous buffers.
Pre-dissolve e.g. 10 mg (5.39 μmol) in 108 μl DMSO - dilute e.g. 10 μl of that stock solution (50 mM) with 9990 μl aqueous buffer to obtain a 50 μM solution. DMSO stock solutions are sterile and can be stored at -20°C for at least 6 months. To avoid too many freeze-thaw cycles, we strongly recommend storage of aliquots.

Application

Kinetic measurement of transglutaminases

Storage

Store at -20°C, desiccate

Note

The molecular weight was corrected to 1853.95, taking into account that A101 traps only one TFA counter ion instead of two counter ions as stated in PDS RN3.1 from 07 May 2014. The presence of one TFA counter ion is valid for all former batches, too.
Background: During the course of our continuous quality assurance process, Zedira developed a novel method to quantify the TFA counter ion content by using a ¹⁹F NMR method according to Little et al. (J. Pharm. Biomed. Anal. 2007, 43, 1324), based on an internal standard.
Please note that neither the synthesis and purification nor the product as such has been changed. Please consider the molecular weight correction if necessary.
