Visit Supplier

The Qubit Protein Detection Kit is a fluorescence-based assay designed to accurately quantify protein concentrations in solution. The kit utilizes a dye that binds specifically to proteins, allowing for precise measurement of protein levels in a sample. This tool provides a simple and reliable method for determining protein concentrations in research and analytical applications.

Protein samples were extracted by using NP40 solution followed manufactory’s protocol (Thermofisher) and protein concentration was determined by using Qubit protein detection Kit (Invitrogen) followed by manufactory’s protocol. Individual samples were run on a single 10 well gel or 12 well pre-made 4–12% gel (Thermofisher). Briefly, samples were prepared on ice (to final volume of 20 μl) and then vortexed and denatured for 10 min at 90 °C. Gels were run with 1X Tris buffered saline-Tween (TBS-T) and proteins transferred onto nitrocellulose membrane (Bio-rad). The membrane was blocked by blocking buffer (Licor) for 1hr at room temperature, washed with TBS-T for 5 min (3X), and incubated with 5ml of N6amt1 (1:250; Santa Cruz) and Beta-actin (1:500; Santa Cruz) or beta-tubulin (1:500; Santa Cruz) antibodies in blocking buffer (Licor) for overnight at 4 °C. The membranes were washed with TBS-T (3X), incubated for 1hr with anti-mouse secondary antibody (1: 15000; Li-Cor) and anti-rabbit secondary antibody (1:15000; Li-Cor) in blocking buffer (Li-Cor), and washed three times with TBST for 10 min (5X) and 20 min (1X). Optical density readings of the membrane were taken using a Li-Cor FX system followed by manufactory’s protocol. Detailed antibody information is attached within Reporting Summary file.

Protein samples were extracted using NP40 solution following the manufacturer’s protocol (Thermo Fisher) and the protein concentration was determined using the Qubit protein detection kit (Invitrogen), also following the manufacturer’s protocol. Individual samples were run on a single 10-well gel pre-made 4–12% gel (Thermo Fisher). Briefly, samples were prepared on ice (to a final volume of 20 μL) and then vortexed and denatured for 10 min at 90°C. Gels were run with TBS-T and proteins were transferred onto a nitrocellulose membrane (Biorad). The membrane was blocked by blocking buffer (LI-COR) for 1 h at room temperature, washed with TBS-T for 5 min (three times) and incubated with 5 mL of 14-3-3 β/α and β-tubulin (control) antibodies (Table S4) in blocking buffer (LI-COR) overnight at 4°C. The membranes were washed with TBS-T (three times), incubated for 1 h with anti-mouse secondary antibody (1:15,000; LI-COR) and anti-rabbit secondary antibody (1:15,000; LI-COR) in blocking buffer (LI-COR), then washed with TBS-T for 10 min (three times) and 20 min (once). Absorbance readings of the membrane were taken using a LI-COR FX system following the manufacturer’s protocol.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
