Strip holders
Two models of strip manifolds
IPG strip manifolds are available in two models:
•
One produced from a ceramic material providing greater temperature uniformity
•
One produced from a light polymeric material for less critical experimentation
Both are designed for analytical analysis using cup application and preparative runs
applying sample to the gel during the rehydration step or by paper bridge loading.
Strip holder
The strip holders are made of aluminum oxide ceramic with electrodes of platinum on
titanium. The ceramic is very brittle so the holders are fragile and must be handled with
care.
The ceramic is treated with a special coating to minimize protein binding and must be
cleaned only with the Ettan IPGphor Cleaning Solution supplied to retain that coating.
Each fixed-length strip holder base holds a single IPG strip throughout rehydration and
isoelectric focusing. A matching length holder is available for each size strip. All strips
(and holders) used at any one time must be of the same length.
Five strip holder lengths are available, 7, 11, 13, 18, and 24 cm, one for each IPG strip
length and a number of pH ranges, several linear and non-linear. Refer to Section 8.3
Ordering information, on page 116.
