MCAT - Lab Techniques (MilesDown)Native-PAGE - correct answer A polyacrylamide gel electrophoresis method for proteins using NON-DENATURING conditions. Proteins keep their native charge and structure so they are separated based on charge and size. SDS-PAGE - correct answer A polyacrylamide gel electrophoresis method for proteins using DENATURING conditions. Sodium Dodecyl Sulfate denatures the proteins and gives the proteins a uniform charge. This allows them to be separated solely on mass, t...

how much BSA is needed to prepare 50 mL of 5 mg/ml of BSA (w/v)? - Answer-(50 mL)(5 mg,mL) = 250 mg a technician is assigned the task of inserting a gene, LanA, into a plasmid to ultimately be expressed as a therapeutic protein in E coli. label the following steps (1-4) in the correct order the technician must perform them to accomplish her task. - Answer-1) design primers to amplify the lanA sequence using polymerase chain reaction (PCR) and perform the PCR reaction 2) digest and provide ...
