I. The modification of pCT5e MH-G3Long MH-G3Short SOE PCR: MH-G3Long[NotI-BamHI], MH-G3Short[NotI-NdeI] Double digest: Conclusion: The new kit(From Weng lab) is weak to extract small DNA fragment from agarose gel.

II. Mouse enterokinase light chain(mEKL)

III. Biotinylation of trx-PD1Ecd-AviTag Dot Blot: ratio of enzyme to POI-AviTag is marked below. 1/10, 1/20, 1/40, 1/60, 1/80 1/100, 1/200, 1/400, 1/600, 1/800 1/1000, 1/2000, 1/4000, 1/6000, 1/8000 1/10000, 1/20000, 1/40000, 1/60000, 1/ /100000, NC PC

When we amplifying the reaction from 50ul to 500ul, the protein precipitate at once. Solution: (with WHF) We find the buffering capacity of 0.5M Gly-HCl is so low that the final reaction pH is nearly 3; 10xBioMixA has been changed to 0.5M Tris-HCl. We will do the above experiment again. If the step is done,we consider the next steps: - Using sephadex G-75 to remove the excess free biotin. - Do a pull down assay to try the effect of biotinlation.

Plan for next week Get the new phagemid.
