Background of FMRP
FMR1 (fragile X mental retardation 1) is a human gene that codes for a protein called fragile X mentalretardation protein, or FMRP. This protein, most commonly found in the brain, is essential for normal cognitive development and female reproductive function. Mutations of this gene can lead to fragile X syndrome, mental retardation, premature ovarian failure, autism, Parkinson's disease, developmental delays and other cognitive deficits. The protein encoded by this gene binds RNA and is associated with polysomes. Additionally, the encoded protein may be involved in mRNA trafficking from the nucleus to the cytoplasm. A trinucleotide repeat (CGG) in the 5' UTR is normally found at 6-53 copies, but an expansion to 55-230 repeats is the cause of fragile X syndrome. Expansion of the trinucleotide repeat may also cause one form of premature ovarian failure (POF1). Multiple alternatively spliced transcript variants that encode different protein isoforms and which are located in different cellular locations have been described for this gene.
Antibody Validation

Figure 1. Western blot analysis of FMRP/FMR1 using anti-FMRP/FMR1 antibody (PB9703).
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 293T whole cell lysates,
Lane 3: human Jurkat whole cell lysates,
Lane 4: human K562 whole cell lysates,
Lane 5: rat brain tissue lysates,
Lane 6: rat liver tissue lysates,
Lane 7: mouse brain tissue lysates,
Lane 8: mouse liver tissue 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-FMRP/FMR1 antigen affinity purified polyclonal antibody (Catalog # PB9703) 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 FMRP/FMR1 at approximately 71-73 kDa. The expected band size for FMRP/FMR1 is at 71 kDa.

Figure 2. IHC analysis of FMRP/FMR1 using anti-FMRP/FMR1 antibody (PB9703).
FMRP/FMR1 was detected in a paraffin-embedded section of human seminoma testis tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH 8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 2 μg/ml rabbit anti-FMRP/FMR1 Antibody (PB9703) overnight at 4°C. Peroxidase Conjugated Goat Anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using HRP Conjugated Rabbit IgG Super Vision Assay Kit (Catalog # SV0002) with DAB as the chromogen.

Figure 3. IF analysis of FMRP/FMR1 using anti-FMRP/FMR1 antibody (PB9703).
FMRP/FMR1 was detected in an immunocytochemical section of Hela cells. Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent (AR0022) for 15 mins. The cells were blocked with 10% goat serum. And then incubated with 5 μg/mL rabbit anti-FMRP/FMR1 Antibody (PB9703) overnight at 4°C. DyLight®488 Conjugated Goat Anti-Rabbit IgG (BA1127) was used as secondary antibody at 1:100 dilution and incubated for 30 minutes at 37°C. The section was counterstained with DAPI. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

5 Customer Q&As for Anti-FMRP/FMR1 Antibody Picoband®
Question
We are currently using anti-FMRP/FMR1 antibody PB9703 for mouse tissue, and we are satisfied with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it possible that the antibody can work on bovine tissues as well?

Asked: 2020-01-24
Answer
The anti-FMRP/FMR1 antibody (PB9703) has not been tested for cross reactivity specifically with bovine tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in bovine you can get your next antibody for free. Please contact me if I can help you with anything.

Question
Would PB9703 anti-FMRP/FMR1 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?
Verified Customer
Verified customer
Asked: 2019-08-26
Answer
It shows on the product datasheet, PB9703 anti-FMRP/FMR1 antibody as been validated on WB. 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
My question regarding product PB9703, anti-FMRP/FMR1 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: 2018-01-01
Answer
We suggest not 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 PB9703 anti-FMRP/FMR1 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.
