Vector/Insertion/Complexity/mRNA source
lambda gt22A/SalI-NotI/5x10[5]/Canton S ovaries, stages 1-14

The available amplified aliquots of the Tolias ovarian gt22A directional
cDNA library were titred at 3 x 10(8) pfu/ml (99% inserts) before freezing.
The original complexity of this sample was 500,000 independent clones
(99.7% inserts).  The 5' end has unique sites for EcoRI and SalI
(GAATTCGTCGACCCACGCGTCCG), the 3' end has a unique NotI site. Use a fresh
Y1090 O/N grown in LB amp (50 ug/ml),  0.2% maltose and 10 mM MgSO4 as
recommended by most protocols.  If you want to screen this library by PCR,
I suggest that you use a small fraction of this aliqout to reamplify and
use only reamplified samples for PCR.
     This library has been widely distributed in the USA, Canada and
Europe.  To conserve the remaining aliquots, please check oogenesis labs in
your area first before requesting it.  If it is not available, please send
us a Federal Express number to facilitate shipment.  When you receive the
library, divide it into 50 ul aliquots in siliconized microfuge tubes, add
one drop of chloroform, store one of the aliqouts at 4 deg C and freeze the
rest at -70 deg C.  When a frozen aliquot is required, thaw, use and store
at 4 deg C but do not freeze again.
