Background Information
Fatty acid desaturase 2 (FADS2) is responsible for the first desaturation reaction in the synthesis of highly unsaturated fatty acids (HUFAs), such as arachidonic acid (20:4n-6) and eicosapentaenoic acid (20:5n-3), and is involved in Mead acid (20:3n-9) production during essential fatty acid deficiency (EFAD) (PMID: 29353041). This is important when temperatures changes and the membrane is under distress. It has 4 isoforms and can be detected as 46-52 kDa.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Kristen (Verified Customer) (12-15-2025) | Used to evaluate protein expression of FADS2 in syngeneic mouse melanoma cell lines. Variable expression levels, but correct band size seen in some lines
|
FH Casey (Verified Customer) (11-30-2025) | Needed to use a lower antibody dilution (1:500) to see band
|
FH Haley (Verified Customer) (11-26-2025) | Great reproducible results using this antibody
|
FH Jelan (Verified Customer) (10-31-2025) | We use the antibody FAPS2 across various cell lines that we have lysed to check for bands on our western blot to spot the difference and see if our cell lines accurately over expressed or under expressed certain drug treatments we have treated our cells with.
|
FH Xianfeng (Verified Customer) (02-18-2020) | Works well with overexpressed mouse FADS2 but no signal with endogenouse mouse FADS2.
 |
FH XIANFENG (Verified Customer) (02-06-2020) | Works well with overexpressed mouse FADS2, but does not work with endogenous mouse FADS2 (mouse liver) .
