PRJ002AiptasiaMM Preknockdown experiment sampling after 1 week in ABS and 1 day of recovery
## Objective: Sample individuals that have been treated in ABS, or ABS 2 without the priming for one week , then allowed to recover in Filtered Sewater for a further week in order to determine the the susceptibility of anemones to conditions and test if knockdown remains after one week of ir bacterial abundance increases within that time period
Broader Context
This will serve as preliminary data in a pre-experiment for PRJ002-Aiptasia-MM, which will allow for any needed adjustments to be made after the priming in the main experiment is complete.
Protocol
Samples total were taken at time of sampling SAM143-145 were taken from the ABS 1 plate wells A2, B3, and B1 respectively, SAM_146-148 were taken from ABS2 plate wells B1, A2, and C2 respectively. SAM_149 was taken from the stock tanks to use as a control.
All anemones were homogenized in 300ul of Filtered ASW using a a handheld 1.5ml tube pestle. 50 ul were removed from the tube and used to plate serial dilutions of homogenate on Marine Agar plates at 100 and 10-1 dilutions ( 50ul per plate). Samples were spread using 5 roller beads per plate and passed through a infinity motion 20 times and left in the incubator at 28C for 24 hours. the remaining 250 ul was transferred to a MP Biomedicals Lysing matrix E tube with the glass bead removed. 500ul of DNA/RNA shield was added to the lysing tubes and samples were bead beat at 8 m/s for 60 seconds twice with a five minute pause between the two cycles, then frozen at -80 in Box A until further processing.
