Question

I'm a little confused, the *competitor* web page for D-AP5 (not the sodium
salt) states
"Soluble to 10 mM in water and to 100 mM in 1eq. NaOH"
This is copied and pasted from
http://www.*competitor name*.com/dispprod.php?ItemId=1191, their equivalent of
your ab120003 I think.
Your web page https://www.abcam.com/D-AP5-ab120003.html states....
"Soluble in water to 100 mM"
I have been making (or attempting to make!) 50mM D-AP5 in 18.2MOhm
water to make a stock solution that I aliquot into small samples and
freeze. I then thaw the required amount on the day dilute 1:1000 into
ACSF before using this solution to block NMDA receptors in hippocampal
CA1 slices from young mice (190uM thick). The solution either appears
not to work at all (most of the time) or very well, which is what lead
me to check your solubility data. Again I stress this is NOT the
sodium salt which appears to have the correct solubility on your web
page.
Not trying to pretend I know a lot about solubility and things like
that as I'm not a chemist and only a third year PhD! But would like to
get to the bottom of this to save more wasted time!
Thanks

Answer

We have not previously experienced any issues with D-AP5 (ab120003) and we are confident that it is soluble to 100 mM in water. I noticed that the *competitor name* product page that you linked to was for DL-AP5 rather than D-AP5. DL-AP5 has a lower solubility (soluble to 10 mM in water). This should explain why you thought there was a discrepancy in our solubility data.
Regarding your issues, we recommend wherever possible to prepare and use solutions on the same day. For stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. However before use and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.  Solubility is temperature dependent and as such, cooling or freezing solutions may lead to precipitation of the product from solution. It is therefore essential to ensure that your product is completely re-dissolved before use.
In light of your difficulties we would be happy to offer you free replacement of one vial of  this compound as a special exception.
In order to issue a free of charge replacement I need the lot number, original order number and date.
I am looking forward to your reply and wish you a good weekend.

Question

Hi There,
Just to let you know, I think there may be a mistake in your data
sheet for your D-AP5 (ab120003). You have stated the soubility as
100mM, I think it could be 10mM! Not entirely sure but thats what it
says on the #competitor# website, and the last 6 months of patch clamping
have not being going well with your AP5!!!
Yours,

Answer

Thank you foryour inquiry.

It is regrettable the results with ab120003have not been successful.

I double checked with the lab and the #competitor# Website and I can confirm that D-AP5 (CAS number 79055-68-8) is soluble in water to 100mM.


In order to help with our investigation of this case before deciding how to proceed, I would appreciate if you are able to provide more detail about the experiment that ab120003is used in. This information will also be helpful to our quality monitoring.


I will be pleased to provide a free of charge replacement or credit note if we find the productto be faulty.

Thank you for your time. I look forward to hearing from you with the requested information.
