Our Abpromise guarantee covers the use of ab8340 in the following tested applications.

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

Application Abreviews Notes
IP Use at an assay dependent concentration. Use 15µg for 150 µl tissue (68% of all GABA-A receptors in dodecylsulfate extracts of rat forebrains).
WB 1/1000.

By Western blot, this antibody detects an 50 - 53 kDa protein, corresponding to the expected molecular weight of GABA A receptor beta 2/GABRB2 subunit.


  • Function

    GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel.
  • Tissue specificity

    Isoform 1 and isoform 2 show reduced expression in schizophrenic brain. Isoform 3 shows increased expression in schizophrenic and bipolar disorder brains while isoform 4 shows reduced expression.
  • Sequence similarities

    Belongs to the ligand-gated ion channel (TC 1.A.9) family. Gamma-aminobutyric acid receptor (TC 1.A.9.5) subfamily. GABRB2 sub-subfamily.
  • Cellular localization

    Cell junction > synapse > postsynaptic cell membrane. Cell membrane.

Thank you for the response.

I am very glad that your customer accepts my offer to give ab123288 Anti-GABA A Receptor beta 2 antibodya try. However, can you confirm that theab8340 was on order PO-12345, Abcam reference123456?

Regarding the negative control, we do not have a KO mouse lysate. However, I would suggest checking the UniGene link as can be a good source to choose an appropriate positive or negative control.

I am looking forward to your reply.

Thank you for your reply.

I am sorry that we are not able to provide the sequence in this particular case. We are aware that this is not an ideal situation.Although we are providing the immunogen in many cases, this is not true in these circumstances.

However, both antibodies are not completely without any information regarding the immunogen: both are derived within the cytosolic loop of the rat protein:

ab8340- the immunogen can be found between AA327-451 of the rat protein,
ab4046- the immunogen can be found between AA328-450 of the rat protein

In addition, the article you kindly sent to us contains the following statement: "Lacking the antigen (e.g., if it is a large protein), there are several alternative strategies for establishing staining specificity." Thiskind of information can be found on the datasheetforab4046:

1. The antibody produces one single band

2. We provide next to the positive control brain the negative control in form of a ko-mice lysate, which is givenmore weight than the use of a blocking peptide.

Checking the datasheet, I found that ab4046has beenused six times in references from 2005 to 2012.ab8340 has one reference, but it is the only antibody against this target whichhas been cited.This shows that scientistsare successfully working and publishing with thesetwoantibodies.

I hope the information regarding the ab4046is therefore sufficient for the journal as it fits the required standards mentioned in the article. If this is not the case, please let me know.

Taking your feedback into consideration, that the information for ab8340is not as comprehensive as desired, I would like to offer you a free unit of ab123288 Anti-GABA A Receptor beta 2 antibodyas a gesture of goodwill.

For the future, please always feel free to ask us about additional immunogen or antibody information, e.g. additional images.

I hope this information is helpful to you. Please let me know if this is acceptable for you.

Thank you for your inquiry.

Unfortunately, we are not able to release the immunogen sequence for these particular antibodies as it is proprietary information. Unfortunately, we do not have the corresponding peptides for sale, either.

We aim to provide as much information as possible to our customers, so I am sorry that this has not been possible on this occasion.

If your customer is interested in antibodies with a given immunogen sequence I would suggest ab123288Anti-GABA A Receptor beta 2 antibody

andab104659 Anti-GABA A Receptor beta 3 antibody( for this product, we have the peptide available).

Should you have any further questions, please do not hesitate to contact us.

Thank you for your enquiry. The lysate used to characterize both ab8340 (NB 300-198) and ab8341( NB 300-148) was rat brain (hippocampal) lysate using approximately 5-7 micrograms of tissue per slot. If you have any additional questions, please contact us again.
