How do I know if my GeneChip Scanner 3000 has been enabled for high-resolution scanning that is needed for the Rat 230 2.0 Array?
a. GeneChip Scanner 3000s that were shipped after September 15, 2003 with serial number 502xxx are enabled for high-resolution scanning.

b. GeneChip Scanner 3000s that were shipped prior to September 15, 2003 with serial number 501xxx that have had the GeneChip Scanner 3000 High-Resolution Update installed by an instrument service engineer are enabled for high-resolution scanning. A sticker is applied to the rear of the scanner to indicate that the upgrade has been performed.

c. Contact 888-DNA-CHIP or your local Affymetrix technical support to inquire about a scanner upgrade.
