Target

  • Function
    Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In the brain and peripheral nervous system, NO displays many properties of a neurotransmitter. Probably has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such SRR.
  • Tissue specificity
    Isoform 1 is ubiquitously expressed: detected in skeletal muscle and brain, also in testis, lung and kidney, and at low levels in heart, adrenal gland and retina. Not detected in the platelets. Isoform 3 is expressed only in testis. Isoform 4 is detected in testis, skeletal muscle, lung, and kidney, at low levels in the brain, but not in the heart and adrenal gland.
  • Sequence similarities
    Belongs to the NOS family.
    Contains 1 FAD-binding FR-type domain.
    Contains 1 flavodoxin-like domain.
    Contains 1 PDZ (DHR) domain.
  • Domain
    The PDZ domain in the N-terminal part of the neuronal isoform participates in protein-protein interaction, and is responsible for targeting nNos to synaptic membranes in muscles. Mediates interaction with VAC14.
  • Post-translational
    modifications
    Ubiquitinated; mediated by STUB1/CHIP in the presence of Hsp70 and Hsp40 (in vitro).
  • Cellular localization
    Cell membrane > sarcolemma. Cell projection > dendritic spine. In skeletal muscle, it is localized beneath the sarcolemma of fast-twitch muscle fiber by associating with the dystrophin glycoprotein complex. In neurons, enriched in dendritic spines.

Images

  • Immunohistochemistry was performed on normal biopsies of deparaffinized Rat cerebellum tissue. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer and microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:200 with a Rabbit Polyclonal Antibody recognizing nNOS (ab3511 ) or without primary antibody (negative control) overnight at 4�C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of mouse skeletal muscle tissue sections labeling nNOS (neuronal) with ab3511 at 1/400 (left). Antigen retrieval was performed using 10M sodium citrate (pH 6.0) buffer, microwaved for 8-15 minutes. Tissues were blocked in 3% BSA in PBS for 30 minutes at room temperature. A biotin-conjugated secondary antibody was used. Right - negative control.

  • Western blot analysis of nNOS was performed by loading 40 ?g of Mouse (Lane 1) and Rat Brain (Lane 2) tissue lysate onto a 4-12% Bis-Tris polyacrylamide gel. Proteins were transferred to a Nitrocellulose membrane. Membranes were probed with a rabbit polyclonal antibody (ab3511) recognizing nNOS at a dilution of 1:1000.

Answer

Thank you for your reply.

As for ab72428, I will need to check with the lab regarding tested tissue,localization of staining and potential cross-reactivity with eNOS and iNOS. I will letyou know what I find out. Thank you for your patience.

As for references, we list them on the online datasheet in a tab called "Specific references" if we are aware of any. Also, customer reviews can contain testing data on new species and those would be listed in the tab "Abreviews" on the online datasheet.

For ab72428:

Abreviews: wehave not yet received Abreviews from other customers for this antibody.

As for ab106417, a rabbit polyclonal, yes, high background due to crossreactivity of the secondary antibody (anti-rabbit) with the endogenous rabbit IgG (just as mouse-on-mouse staining)could potentially pose a problem, but there are ways to get around this.
Here is our mouse-on-mouse staining advice:
https://www.abcam.com/index.html?pageconfig=resource&rid=11465
which can be adapted to rabbit-on-rabbit staining as well.

I hope this information is of some help so far. I will be in touch with more details soon.
In the meantime, please do not hesitate to contact us if you need any more advice or information.

Answer

Thank you for contacting us.

We have 3 antibodies that were tested and are guaranteed (https://www.abcam.com/Abpromise) for IHC-P and rabbit samples: ab1376,ab6175 and ab72428. I would recommend trying one of thosethat were tested as they are covered under our guarantee.
We do not compare antibodies side by side, thus, I have no infomation on which of these antibodies works best in rabbit tissue. If you had unsuccessful experiences with immunogens similar to ab6175 and ab1376, I would suggest to try ab72428.

We have 3 other nNOS antibodies that are tested in IHC-P and predicted to react with rabbit (based on sequence homology) but have not yet been tested in this species:
ab79051, ab106417, ab95436

As for ab3511: This antibody was not tested in IHC-P, thus we do not know how well it would work in this application.

If you decide to try any of the 4 untestedantibodies, you can use our testing discount program. For UNTESTED species and/or applications, we have established a testing discount program. Here is a brief description of how it works:

The testing discount program is for customers who like to use an antibody/protein/kit on an untested species/application. You would purchase the antibody at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody/protein at the full price (100%) of the antibody/protein you have tested, or a full price discount for the amount paid for the kit. The terms and conditions applicable to this offer can be found here: https://www.abcam.com/collaborationdiscount.
This programapplies to ELISA kits and other kits we offer.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
