Background of Fatty Acid Synthase/FASN
Fatty acid synthase (FAS) is an enzyme that in humans is encoded by the FASN gene. It is mapped to 17q25. The enzyme encoded by this gene is a multifunctional protein. Its main function is to catalyze the synthesis of palmitate from acetyl-CoA and malonyl-CoA, in the presence of NADPH, into long-chain saturated fatty acids. In some cancer cell lines, this protein has been found to be fused with estrogen receptor-alpha (ER-alpha), in which the N-terminus of FAS is fused in-frame with the C-terminus of ER-alpha.
Antibody Validation
Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence, and ELISA with known positive control and negative samples to ensure specificity and high affinity, including thorough antibody incubations.

Figure 1. Western blot analysis of FASN using anti-FASN antibody (PB9865).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human Hela whole cell lysates,
Lane 2: human HepG2 whole cell lysates,
Lane 3: human hepatocellular carcinoma tumor tissue (HCCT) lysates,
Lane 4: human 293T whole cell lysates,
Lane 5: human MCF-7 whole cell lysates,
Lane 6: human RT4 whole cell lysates,
Lane 7: human A549 whole cell lysates.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-FASN antigen affinity purified polyclonal antibody (Catalog # PB9865) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for FASN at approximately 273 kDa. The expected band size for FASN is at 273 kDa.

Question
Will anti-Fatty Acid Synthase/FASN antibody PB9865 work on primate WB with liver?
Z. Johnson
Verified customer
Asked: 2020-03-16
Answer
Our lab technicians have not validated anti-Fatty Acid Synthase/FASN antibody PB9865 on primate. You can run a BLAST between primate and the immunogen sequence of anti-Fatty Acid Synthase/FASN antibody PB9865 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated primate samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in primate liver in WB, you can get your next antibody for free.

Question
Does PB9865 anti-Fatty Acid Synthase/FASN antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?
Verified Customer
Verified customer
Asked: 2019-06-17
Answer
As indicated on the product datasheet, PB9865 anti-Fatty Acid Synthase/FASN antibody as been tested on ICC. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

Question
Can you help my question with product PB9865, anti-Fatty Acid Synthase/FASN antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?
Verified Customer
Verified customer
Asked: 2017-09-22
Answer
It is not recommended storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free PB9865 anti-Fatty Acid Synthase/FASN antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.
