Best practices:

• Prior to starting the Infinium assay, download DMAPs to confirm availability.

• Make sure that the two types of information entered in the Primary and Verification fields are associated (eg, the correct Box ID for a barcode, or the correct Sales Order number for Box ID).

• Make sure the download location (computer or network) has sufficient disk space.

• For large orders of BeadChips or to improve download speed:

  • Download in smaller batches using the Box IDs or barcodes in the Primary Field, rather than the Sales Order number or Purchase Order number.

  • Download to the local drive instead of a network drive.
