Title: Pin plate for use in array printing and method for making the pin plate
Inventor: BRADY MICHAEL DONOVAN
IPC: G03F7/004
Filed: 2002-08-21
Abstract: A pin plate used to print a high density array printing of materials such as biological inks and a method for manufacturing the pin plate are described herein. The pin plate can be manufactured by coating a top surface of a silica wafer with a substantially thick layer of photoresist material. Next, a photolithography process is used to remove selected areas of the photoresist material from the silica wafer. Thereafter, a reactive ion etching process is used to form the pins in the silica wafer by etching away a predetermined amount of the top surface from the silica wafer that is not covered by the photoresist material. Afterwards, the remaining photoresist material is removed from the silica wafer which now resembles the pin plate.

Filed: 2001-05-01
Abstract: The 28-kDa outer membrane proteins (P28) of Ehrlichia chaffeensis are encoded by a multigene family consisting of 21 members located in a 23-kb DNA fragment in the genome of E. chaffeensis. Fifteen of these proteins are claimed herein as novel sequences. The amino acid sequence identity of the various P28 proteins was 20-83%. Six of 10 tested p28 genes were actively transcribed in cell culture grown E. chaffeensis RT-PCR also indicated that each of the p28 genes was monocistronic. These results suggest that the p28 genes are active genes and encode polymorphic forms of the P28 proteins. The P28s were also divergent among different isolates of E. chaffeensis. The large repertoire of the p28 genes in a single ehrlichial organism and antigenic diversity of the P28 among the isolates of E.chaffeensis suggest that the P28s may be involved in immune avoidance.
