  • This lab involves screening transformed E. coli colonies for the presence of the CaMPARI insert using colony PCR and gel electrophoresis. It also includes analysis of Sanger sequencing data to confirm insert identity and orientation using SnapGene. Students identify errors such as truncations, SNPs, or misalignments that may affect downstream expression.

  • This lab involved assembling the pHLsec-CaMPARI plasmid using Gibson Assembly, followed by transformation into competent E. coli cells. Students compared experimental and control plates to assess colony growth, verify plasmid uptake, and troubleshoot transformation success. Accurate labeling, colony counting, and understanding of antibiotic selection were key components.

  • This lab introduces SDS-PAGE to separate bacterial proteins by molecular weight following induction with glucose, lactose, or IPTG in cells carrying the pET41a-CaMPARI vector. It also covers the transfer of proteins to a PVDF membrane in preparation for Western blotting. The experiment sets the stage for identifying GST::CaMPARI expression and evaluating the effectiveness of different inducers.

  • This lab introduces SDS-PAGE and membrane transfer techniques to begin visualizing CaMPARI protein expression using the pET41a-CaMPARI bacterial expression vector. It prepares students for Western blotting by identifying protein bands and assessing sample quality post-induction with lactose and IPTG. These results lay the foundation for confirming protein identity and expression efficiency in subsequent labs.

  • This lab focuses on purifying the CaMPARI protein using affinity chromatography, testing its calcium responsiveness through in vitro manipulation with CaCl₂ and EGTA, and quantifying protein concentration using the Bradford Assay. The lab integrates key biochemical techniques to evaluate CaMPARI’s behavior in response to calcium, laying the groundwork for later experiments involving photoconversion and mammalian expression systems.

  • In this lab, we investigated the fluorescence response of CaMPARI-expressing cells to two treatments: ATP and Tris-HCl, which will serve as controls for our pharmacology experiment next week. ATP is expected to increase intracellular calcium levels, which should cause a fluorescence shift in CaMPARI due to its calcium-dependent photoconversion. Tris-HCl serves as a negative control and is not expected to alter intracellular calcium levels, so no significant change in fluorescence is antici...

  • In this lab, we used three protocols: Gibson Assembly, Transformation, and the Interim Lab. Each of these protocols was critical for progressing our CaMPARI project: Gibson Assembly was used to combine our linear DNA fragments into a complete plasmid (pHLsec-CaMPARI). Transformation allowed us to introduce this newly assembled plasmid into competent E. coli DH5-alpha cells. The Interim Lab helped us track our progress and ensure our plasmid was constructed correctly before proceeding to...
