Zygotes were lysed with SDS sample buffer (100 zygotes per sample) and heated for 5 min at 95 °C. Total zygotes proteins were separated by SDS-PAGE and electrophoretically transferred to PVDF membranes (Millipore, USA), followed by blocking in TBST containing 5% defatted milk (BD, USA) for 30 min. First, the membranes were incubated with primary antibodies overnight at 4 °C. Then, the membranes were washed in TBST, and incubated with a HRP-linked secondary antibody for 1 h at room temperature, followed by washing with TBST three times. Finally, bounding antibodies were detected using SuperSignal WestFemto maximum sensitivity substrate (Thermo Fisher, USA). The primary antibodies used and dilution factors are anti-DDB1 (Epitomics, #3821-1, 1:10000) and anti-FLAG antibodies (Sigma, #F3165, 1:3000). The secondary antibody was HRP-conjugated anti-rabbit/mouse IgG (Jackson ImmunoResearch Laboratories).

The EV71-infected lysates were separated on 15% SDS-PAGE under reducing conditions, which were transferred into PVDF membranes. After blocking with 5% skimmed milk in PBS at room temperature (25 °C) for 1 h, the scFv antibodies were detected using mouse anti-HA tag (Proteintech, Rosemont, IL, USA) and HRP-conjugated rabbit anti-mouse IgG (Jackson ImmunoResearch, West Grove, PA, USA) antibodies. The membranes were developed using the 3,3ʹ-diaminobenzidine (DAB) reagent. Similarly, the IgY was detected using HRP-conjugated donkey anti-chicken IgY (Jackson ImmunoResearch, West Grove, PA, USA). For the cross-reactivity assay, the selected scFv antibodies (10 μg/mL) were added and detected by mouse anti-HA tag and HRP-conjugated rabbit anti-mouse. Other steps, such as blocking, washing, incubation and color development steps were performed as described above.

Functional Analysis of LMF1 Variants

Check if the same lab product or an alternative is used in the 5 most similar protocols
LMF1 variants were functionally analyzed using a second-generation LMF1 activity assay based on the reconstitution of LPL maturation in LMF1-deficient HEK293 cells generated by CRISPR-mediated mutagenesis 15 (link). Cells were cotransfected in quintuplicates with mixtures of V5-LPL, wild-type or mutant LMF1 constructs generated by site-directed mutagenesis and a firefly luciferase vector (pGL3-Control, Promega, USA) for transfection normalization. To allow precise quantitative assessment of LMF1 protein levels, LMF1 variants were expressed as fusion proteins with Gaussia luciferase at the N-terminus (Gluc-LMF1). At 24 h posttransfection, 10 U/ml heparin was added to media and after 30 min cells were incubated with a fresh aliquot of heparin-containing media for 2 hours. Media were harvested for fluorometric LPL activity assay (Cell Biolabs, USA) and immunoblot analysis, and cells were lysed for dual-luciferase reporter assay (Promega, USA). LMF1 activity was calculated as the ratio of LPL activity in the media and intracellular LMF1 protein amount (i.e. Gaussia luciferase activity). For the analysis of LPL mass in cell culture media, 5 μl samples were separated by SDS-PAGE and immunoblotted with anti-V5 (1:10,000; Life Technlogies, USA) and HRP-conjugated rabbit anti-mouse IgG (1:100,000; Jackson ImmunoResearch, USA) antibodies.

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.
