I'm not sure if they have mouse data, but for human, you can download from this link below.

http://support.illumina.com/array/array_kits/infinium_humanmethylation450_beadchip_kit.html

Click 'Infinium HumanMethylation450K v1.2 Product Files', then you will see the manifest file in csv format.

I don't think they do a mouse array. This Illumina page http://support.illumina.com/downloads/infinium_humanmethylation450_product_files.html has manifest files (in csv and bpm format) for the human array, and an excel file with the explanation of the column headers for the manifest file.

Dear Mastal511, do you know how we can download these files? They are not available for download. "This system is for the use of authorized users only. " Thank you.
