Human Sirtuin 2/SIRT2 Biotinylated Antibody

Detection of Sirtuin 2/SIRT2 by Western Blot

SIRT2 expression is increased in free fatty acid (FFA)-exposed tolerant RAW 264.7 cell macrophages (RAW) cells. Bovine serum albumin (BSA: vehicle for free fatty acid) or stearic acid (free fatty acid: FFA)-exposed RAW264.7 cell macrophages (RAW) were stimulated with either one or two doses of the LPS; second dose at indicated time points after 1st LPS. (A) TNF-alpha mRNA expression was evaluated by qRT–PCR analysis. (B) SIRT2 protein expression was detected by Western blot in BSA- or FFA-exposed RAW cells following a single dose of the LPS stimulation for indicated time periods. GAPDH was used as the loading control. (C) Western blot image quantification using image-J software (n = 3 each group; * p < 0.05). SIRT2 protein expression was normalized to GAPDH. (D,E). To inhibit SIRT2, after 4 h of 1st LPS exposure, cells were treated with SIRT2 inhibitor AK-7 (25 µM) and incubated further for 20 h in the presence or absence of the second dose of the LPS. TNF-alpha protein released in the cell culture media from FFA-exposed sensitive and tolerant cells was evaluated by ELISA. (* p < 0.05). IL6 (Figure 1E) protein released in the cell culture media from FFA-exposed sensitive and tolerant cells evaluated by ELISA. (* p < 0.05).

(B) PFKP western blot image quantification of PFKP protein in vehicle vs. ethanol exposed WT-BMDM, Y axis represents fold of vehicle-LPS (fold of vehicle control) (n = 4 blots; * p < 0.05). (C) PFKP expression in Ethanol-exposed WT-BMDM and SIRT2KO-BMDM ± LPS. (D) Western blot image quantification of PFKP protein in ethanol exposed WT-BMDM and SIRT2KO-BMDM. Y axis represents fold of Ethanol-exposed WT-LPS (fold of WT- ethanol control) (n = 4 blots; * p < 0.05). (E) PFKP expression in Ethanol-exposed WT-BMDM treated with AK-7 or DMSO ± LPS. (F) Western blot image quantification of PFKP in AK-7 vs. DMSO treated-Ethanol-exposed WT-BMDM ± LPS, Y axis represents fold of Ethanol-exposed WT-LPS (fold of WT- ethanol control) (n = 4 blots; * p < 0.05).
