Figure 3. Deconvoluted ESI-MS spectra of hNTAN1.
(A) hNTAN1 expressed from pNTANFLAGSII and isolated using tandem affinity purification (See “Experimental Procedures”). (B) hNTAN1 expressed from pNTAN2FLAGSII and isolated with identical tandem affinity purification protocol. Samples were analyzed in 50mM Tris-HCl, 150mM NaCl, 1mM EDTA, 0.5mM dTT, pH 7.5. Calculated masses of observed species: hNTAN1 – 37,026 Da; L-Met-L-Gly-hNTAN1 – 37, 214 Da.
