Rabbit anti scd1

Manufactured by Cell Signaling Technology
Sourced in United States

Rabbit anti-SCD1 is a primary antibody that specifically binds to the Stearoyl-CoA Desaturase 1 (SCD1) protein. SCD1 is an enzyme that catalyzes the rate-limiting step in the synthesis of monounsaturated fatty acids. This antibody can be used in various research applications to detect and study the SCD1 protein.

We obtained fatty acids (FAs) from Nu-Chek Prep, Inc.; radiolabeled S-35 methionine from Perkin-Elmer (cat. no. NEG709A500UC); SCD1 inhibitor (A939572; cat. no. 19123), Nonidet P-40 (NP-40; cat. no. 600009) and Protein Synthesis kit (cat. no. 601100) from Cayman Chemicals; rabbit anti-YB-1 from ProteinTech; mouse anti-β-actin from Millipore Sigma; rabbit anti-SCD1 from Cell Signal; YB-1-myc plasmid from Addgene; non-targeting control siRNA and YB-1 siRNAs from Qiagen; FA-free BSA from Sigma-Aldrich; Protease inhibitor cocktail from Roche; Fetal Calf serum (FCS) and Delipidated fetal calf serum (DFCS) from Gemini Bio. All FAs added into culture media were conjugated to BSA as previously reported (10 (link)).

Protein extracts of cells were prepared using RIPA buffer containing protease inhibitor cocktail, and protein concentrations were measured using a BCA kit (Pierce). One hundred micrograms of protein was resolved by electrophoresis in 8% SDS‐PAGE gel and blotted to PVDF membranes (Invitrogen). Membranes were incubated with indicated primary antibodies overnight at 4°C and then with an anti‐rabbit HRP‐conjugated secondary antibody (1:3000; Santa Cruz Biotechnology) for 2 hours at room temperature. The primary antibodies used in this study were rabbit anti‐FAS (1:1000; Cell signaling), rabbit anti‐SCD1 (1:500; Cell signaling), rabbit anti‐FADS2 (1:1000; Abcam), rabbit anti‐COX2 (1:1000; Abcam), and anti‐β‐actin (1:2000; Santa Cruz Biotechnology) as a loading control. HRP activity was measured using Supersignal West Pico Chemiluminescent Substrate kit (Thermo Fisher Scientific).

Naïve CD4+ T cells were purified from WT or BCL6 KO mice with naïve CD4+ T-cell isolation kit (Miltenyi Biotec). Then, the cells were activated and cultured under the TFH polarizing condition as above. The cultured cells were lysed in sample lysis buffer (Cell Signaling Technology) with a protease inhibitor cocktail (Thermo Scientific) and incubated on ice for 30 min. Proteins in the supernatants were heat denatured, separated by 4% to 12% gradient Bis-Tris gel (Invitrogen) and transferred into a nitrocellulose membrane (Bio Rad). Membrane was blocked with 5% of nonfat milk in TBST for 1 h at RT. After washing with TBST (Tris-buffered saline with 0.1% Tween 20), membrane was incubated with following primary antibodies for overnight: Rabbit-anti SCD1 (Cell signaling), rabbit-anti ATF4 (Cell signaling) or mouse-anti actin (Santa Cruz). Membrane was then rinsed with TBST and incubated with the HRP-conjugated secondary antibodies (Promega) for 1 h at RT. ECL kit (Thermo) was used for film (Fisher Scientific) development.

The cells were lysed with RIPA buffer (Beyotime, Shanghai, China) containing 1X PMSF and a protease inhibitor cocktail. After centrifugation at 4 °C and 12,000× g for 15 min, the concentration of proteins in the supernatant was determined using a Piece BCA protein assay kit (Thermo Fisher Scientific Inc., Waltham, MA, USA). The proteins were separated using 10% sodium dodecyl-sulfate-polyacrylamide gels. Thereafter, they were transferred onto a PVDF membrane using a transfer apparatus, and after blocking with 5% skimmed milk, the membrane was incubated with the primary antibody overnight at 4 °C. The primary antibodies, rabbit anti-EGFR, rabbit anti-phospho-EGFR, rabbit anti-FASN, rabbit anti-LIPIN1, rabbit anti-Insig1, rabbit anti-SCD1, rabbit anti-SREBP1, rabbit anti-pAMPK, rabbit anti-p-AKT, rabbit anti-p-PI3K, and mouse anti-GAPDH, were purchased from Cell Signaling Technology (Danvers, MA, USA). Further, rabbit anti-Srebf1 was purchased from Abcam (Cambridge, MA, USA), while goat anti-rabbit IgG and goat anti-mouse secondary antibodies were purchased from Proteintech (Rosemont, IL, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
