Circularization Optimization Testing (Started Monday)
Library Prep (Started Yesterday)
- Ethanol Precipitation
- Centrifuge for 25 minutes at 12000 rpm at 4C
- Remove supernatant and add 750 uL 70% EtOH
- Centrifuge for 12 minutes at 12000 rpm at 4C
- Remove supernatant and spin in vacuum centrifuge for 10 minutes
- Add 30 (20 for NTC) uL nfH2O to resuspend; pool samples A-C by reusing the water
Results
30 uL 58.8 ng/uL
Antibody Binding Test
Test for antibody binding and amplification. I'll use a similar protocol to 10-21 which uses takes time points but I'll also be using the standard beads protocol (some modifications).
Sample | BSA Ab | BSA-Biotin | Dilution | Dilution Amount |
Sample 1 (AB) | X | X | 0 | 2 ug |
Sample 2 (AB) | X | NA | None | |
Sample 3 (AB) | X | 0 | 2 ug | |
Sample 4 (AB) | X | X | 2 | 20 ng |
Sample 5 (AB) | X | X | 4 | 200 pg |
- Template-Bead Binding
- Suspend 2 uL (8 ug) beads per sample in 100 uL wash buffer
- Apply magnet for 30 sec and remove supernatant
- Add 2 uL 2 mg/mL biotin-BSA per sample to bead solution; incubate at RT for 5 min
- Wash beads with 100 uL wash buffer; vortex to suspend; apply magnet and remove supernatant
- C Probe Hybridization
- Combine 2 uL of BSA Ab-AB mix (75 ug/uL stock) and 3 uL bead wash buffer into a 0.2 mL tube
- Incubate at RT for 1.5 hours with agitation
- Add 100 uL of wash buffer; take 10 uL as a time point
- Wash beads with 100 uL wash buffer; apply magnet and remove supernatant
- Repeat wash step above
- Add 100 uL cold Low Salt Buffer; take 10 uL as a time point
- apply magnet and remove supernatant
- Latch and Padlock Hybridization
- Add 2 uL correct latch (10 uM stock) and 2 uL 10 uM Padlock0201 to each sample to a fresh 0.2 mL tube
- Tech Rep A-Latch0001
- Tech Rep B-Latch0002
