  • Description
    Rabbit polyclonal to L Glutamate
  • SpecificityThe antibody is calibrated against a spectrum of antigens to assure hapten selectivity. No measurable cross-reactivity (<1:1000) was detected against glutamate in peptides or proteins. Fixed tissue cross-reactivity was tested with known targets at the recommended dilution. No measurable glutaraldehyde-fixed tissue cross-reactivity (<1:1000) was detected against L-alanine, gamma-aminobutyrate, D/L-aspartate, agmatine, guanidine, D/L-arginine, L-citrulline, L-cysteine, D/L-glutamine, glutathione, glycine, L-lysine, L-ornithine, L-serine, taurine, L-threonine, L-tryptophan, L-tyrosine. Modest cross-reactivity (1:20) was detected against D-glutamate. Significant cross-reactivity (1:8) was detected against free NAAG in competition assays (NAAG is not retained in aldehyde-fixed tissue).

  • Immunogen

    L-glutamate conjugated to glutaraldehyde

  • General notesThe product is optimized for HPI/EHPI with gold or fluorescence detection using etched plastic sections. Filter diluted reagents with 0.2 mm syringe filters before use on EM grids. Enzyme-linked visualizations can be used but will compress the signal dynamic range and are less sensitive.



Our Abpromise guarantee covers the use of ab9440 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Notes
IHC-FoFr Use at an assay dependent dilution. Use with frozen or vibratome sections is possible but will not yield optimal images as IgGs penetrate aldehyde cross-linked tissue poorly and most amino acids are present at such high levels that prozone effects occur.
IHC-Fr Use at an assay dependent dilution.
ICC 1/100. See protocol. OPTIMAL FIXATION: 0.1-2.5% glutaraldehyde,1% formaldehyde using HPI protocol (The antisera targets the glutaraldehyde conjugate of the hapten). All procedures may be carried out at room temperature. MINIMAL GLUTARALDEHYDE: 0.00% using minimum glutaraldehyde Enhanced HPI (EHPI) protocol with 4% formaldehyde.
Immunomicroscopy Use at an assay dependent dilution.
IHC-P Use at an assay dependent dilution.

  • ab9440 staining L Gluramate in Mouse retina tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with methanol, permeabilized with 0.025% TBS-Triton X-100 and blocked with 5% serum for 1 hour. Samples were incubated with primary antibody (1/100 in PBS + 1% BSA) for 18 hours at 4°C. An Alexa Fluor® 594-conjugated Goat anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody.

Thanks for your call today and for your patience while I have looked into your question. I found that the antibody ab8893 does not react with free L-glutamate so I don't believe it will be suitable for the ELISA assay that you are planning. We d...

I have received some further information regarding this antibody from the priginator. Ab9440 does not bind any anti-mouse product that has been tested. The only possible explanation is that the antibody was denatured and that it exposed a non-specific ...
