    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

    We are constantly working hard to ensure we provide our customers with best in class antibodies. As a result of this work we are pleased to now offer this antibody in purified format. We are in the process of updating our datasheets. The purified format is designated 'PUR' on our product labels. If you have any questions regarding this update, please contact our Scientific Support team.

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

    • Involvement in disease

      Defects in OTX2 are the cause of microphthalmia syndromic type 5 (MCOPS5) [MIM:610125]. Microphthalmia is a clinically heterogeneous disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues. Up to 80% of cases of microphthalia occur in association with syndromes that include non-ocular abnormalities. MCOPS5 patients manifest unilateral or bilateral microphthalmia/clinical anophthalmia and variable additional features including coloboma, microcornea, cataract, retinal dystrophy, hypoplasia or agenesis of the optic nerve, agenesis of the corpus callosum, developmental delay, joint laxity, hypotonia, and seizures.

      Question

      Here is the link to ab92515 ( https://www.abcam.com/Otx2-antibody-EPR3347-ab92515.html) The western has a single band close to the 25kD marker band.    While the ab21990 has two bands one just above 25kD and one at 37kD. Since 21990 detects both OTX1 (37kD) and OTX2 (32kD) I assume my lower band is OTX2. But if ab92515 detects both proteins then why don’t we see two bands?   Whereas ab76748 that you suggested previously doesn’t have any western images in the datasheet.   I am trying to estimate amounts of OTX2 only. And this is important hence all the questions.

      Asked on Feb 14 2012

      Answer

      Thank you for getting back to me with these questions.

      I have been under the assumption that you havwe been using ab21190 for your experiments, have you been using ab92515 as well?Based on sequence homology ab92515 will recognize both proteins. The absence of a second band in the image is unresolved but may be due to poor separation or extrememly low levels of Otx1 in the sample.

      Using ab21190 the lower band will be Otx2 which, in either isoform, has a lower molecular weight that Otx1. (http://www.uniprot.org/uniprot/P32243&http://www.uniprot.org/uniprot/P32242).

      Although ab76748 does not have any western blot images in the datasheet we have been assured that the immunogen used for this has no cross reactivity to Otx1.This product is guaranteed to work in western bloton ​human tissues and is covered by our Abpromise for a period of six months. Since we have been unable to resolve this problem, if you have purchased this product within the last 180 days, I would be happy to either send this replacement antibody or to process a refund. If you could please supply me with your Abcam order confirmation number for the purchase of ab21190 I can begin to process this replacement,

      Question

      How about ab92515? Is there a reason you have not mention this Antibody – except that it is monoclonal and the others polyclonal? Does the immunogen cross react ? It has images that seem to indicate specificity to OTX2 only,  in a western.

      Asked on Feb 10 2012

      Answer

      Thank you for contacting us.

      The immunogen for ab92515 shares 100% identity with OTX1, so cross reactivity is predicted.


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

      Asked on Feb 08 2012

      Answer

      Thank you for contacting us.

      I am sorry that you have found this product unsatisfactory following its recent target refinement. As we discussed on the phone the sequence for ab21990 is shared by both OTX1 and OTX2. It was because of this that we have changed the targets.

      We have other products which has been guaranteed to work in WB and ICH on human tissue. One such product is ab76748. According to information that I have recieved form the lab, this antibody is specific to Otx2 only with no cross reactivity with Otx1. The immunogenic peptide was selected from specific domains of Otx2.


      Another product I would like to mention is ab92326. The immunogen for this OTX2 antibody shares 81% identity with OTX1, so the antibody is not predicted to cross-react with OTX1. However, it is not guaranteed without testing

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