Analyzing SDS PAGE Gel results

• Danny ran the SDS PAGE gel for the honeybee purification protocol on 7/30 and Megan stained the gel for visualization of 7/31.
  • The gel was run, and then stored overnight in destain buffer due to logistical reasons before being stained the next day.
• Here is the gel
  

  Fig. 1 Expected size of product is 40 kDa (lane 7). Lane 8 is BSA protein positive control, and lane 9 is Biorad dual color ladder. From lane 1-9 F1,S1,F2,F3,S2,S3, Final product, positive control, and ladder (see table)
• Refer to 7/29 for more detailed description of when each fraction was taken.

F1 (lane 1)	Full cell lysate using BugBuster lysis system
S1 (lane 2)	Supernatant after spinning down full cell lysate
F2 (lane 3)	Full cell lysate #2 after resuspending pellet in Bugbuster
F3 (lane 4)	Full cell lysate #3 after adding lysozyme and DNase
S2 (lane 5)	Supernatant after first wash step.
S3 (lane 6)	Supernatant after second wash step
Final product (lane 7)	Purified inclusion body in SDS
positive control (lane 8)	BSA positive control
ladder (lane 9)	BioRad dual color ladder
