Phospho-Stat3 (Tyr705) (D3A7) XP® Rabbit mAb #9145
Figure 1. Western blot analysis of HeLa cells, untreated or treated with IFN-α comparing lots 1, 2, 3, and 8 of #9145, showing that signal remains consistent from lot to lot. Note: Recommended dilution for western blot was changed to 1:2000 with release of lot 3.
Phospho-p44/42 MAPK (Erk1/2) (Thr202/Tyr204) (D13.14.4E) XP® Rabbit mAb #4370
Figure 2. IHC analysis of adjacent sections of paraffin-embedded human colon carcinoma using #4370 lot 7 at a 1:400 dilution (upper left), #4370 lot 9 at a 1:200 dilution (upper right), #4370 lot 9 at a 1:400 dilution (lower left), and #4370 lot 9 at a 1:800 dilution (lower right). The recommended dilution for lot 9 remained 1:400.
Jak2 (D2E12) XP® Rabbit mAb #3230
Figure 3. Western blot analysis of K562 cells comparing lots 1, 3, and 5 of #3230, showing that signal remains consistent from lot to lot.
