  • ab46182 staining Aquaporin 4 in mouse RAW 264.7 cells by Immunocytochemistry/ Immunofluorescence.
    Cells were fixed with paraformaldehyde and blocked with 10% serum for 20 minutes at 24°C. Samples were incubated with primary antibody (1/100 in PBS) for 16 hours at 4°C. An Alexa Fluor® 488-conjugated goat anti-rabbit polyclonal (1/1000) was used as the secondary antibody.

Question
Answer

We recently compared this antibody against two other antibodies to Aquaporin 4 and they all gave a single band at about 46kDa. However a doublet at 46/48kDa is commonly seen when blotting for this target so if this is what you are seeing then I feel this data to be reasonable.

Answer

Thank you for your further questions.

I can confirm the following prices:
CD14 antibody [5A3B11B5] (ab36595) 100 ul £227.00
CD14 antibody [7] (ab49755) 200 ug £227.00
Delivery: £16.00 to United Kingdom

This information can be found on the individual online datasheets. Please ensure toselect the correct countryfrom thedropdown menu at the top right corner of the webpage. The correct price for the product and delivery charge in the UK will then show at the top of the page.

Regarding which of these antibodies is best for parafin embedded eye sections, I am sorry that neither of these CD14 antibodies have specifically been tested on eye sections as far as we are aware. I would like to reassure you that our antibodies have all been tested successfully and would be covered by our 6 month guarantee in the applications and specieslisted on the datasheets. Therefore, any CD14 antibody tested in thespecies and application you are using should be suitable for your applications. Also, although we produce many in-house antibodies, we obtain other antibodies from a wide range of sources. Therefore, comparison experiments will not often have been done.

If you wish to be more certain, I can suggest choosing the antibody that has been best characterized. By this I mean the antibody that has been tested in the most applications and has the most data available (on the datasheet).

I hope this will be helpful. Should you have any further questions please do not hesitate to ask.

Answer

Thank you for your enquiry which has been forwarded to the scientific support team.

I believe our customer service team have already provided a quotation for you. I can confirm that prices are also available on the online datasheets.

Regarding the IHC application, I can confirm thatab46182is not tested in paraffin embedded sections, this would be indicated by 'IHC-P'.

I am pleased to let you know that Epitomics is now an Abcam company, and ab128906 5582-1 Anti-Aquaporin 4 antibody [EPR7040] is tested in IHC-P and in rat and human samples. so this is suitable and covered by our 6 month guarantee for IHC-P.

I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.
