5 Customer Q&As for Anti-MSK2 (Ab-568) RPS6KA4 Antibody


Will A05545 anti-MSK2 (Ab-568) antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Verified customer

Asked: 2020-01-23


As indicated on the product datasheet, A05545 anti-MSK2 (Ab-568) antibody as been tested on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

We are currently using anti-MSK2 (Ab-568) antibody A05545 for human tissue, and we are content with the WB results. The species of reactivity given in the datasheet says human, mouse. Is it likely that the antibody can work on goat tissues as well?

Verified Customer

Asked: 2019-09-18


The anti-MSK2 (Ab-568) antibody (A05545) has not been tested for cross reactivity specifically with goat tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in goat you can get your next antibody for free. Please contact me if I can help you with anything.

Can you help my question with product A05545, anti-MSK2 (Ab-568) antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?

O. Parker

Verified customer

Asked: 2018-06-26


We do not advise storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free A05545 anti-MSK2 (Ab-568) antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.

Will anti-MSK2 (Ab-568) antibody A05545 work on zebrafish WB with brain?

Verified Customer

Verified customer

Asked: 2017-07-28


Our lab technicians have not tested anti-MSK2 (Ab-568) antibody A05545 on zebrafish. You can run a BLAST between zebrafish and the immunogen sequence of anti-MSK2 (Ab-568) antibody A05545 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated zebrafish samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in zebrafish brain in WB, you can get your next antibody for free.
