Isoallolithocholic acid (3β-Hydroxy-5α-cholanic acid) is a bile acid metabolite and T-cell modulator with anti-inflammatory activity, associated with human immune homeostasis.

X-press Tag is an N-terminal leader peptide; this N-terminal peptide contains a polyhistidine sequence, the Xpress epitope (part of bacteriophage T7 gene 10 protein) and an enterokinase cleavage site. Anti-Xpress antibodies recognize the Xpress epitope sequence found in this leader peptide.

AGK7 is an inactive control of AGK2, a selective SIRT2 inhibitor that selectively inhibits SIRT3 over SIRT1 and SIRT2 (IC50 = >5 μM, >50 μM and >50 μM for SIRT3, SIRT1, and SIRT2, respectively).
