Western blot of ENaC protein

Hi, BiCell,

I believe the new purification method worked. In the blot below, we transfected HEK cells with mouse ENaC (alpha subunit has a V5 tag at the C-terminus).
We included a negative control (plain HEK cell lysates) and a positive control (alpha pulldown by V5 antibody). We can see that the purified #65 recognizes a specific
band in the HEK+ ENaC lysates, which is the same size as the V5 IP and the correct size for ENaC alpha.
This is really exciting, but we would like to try if the antibody can recognize ENaC alpha in the native tissues. We will update you with the new data.

Best, Shujie

    Hi BiCell,

    I received the antisera and tested them with WB. One of them #65 looks promising. The expected bands are marked with green arrows. These bands are weak but specifically detected only in cells transfected with mouse ENaC.
    I suggest we focus on this clone in the next step of purification. Let me know your thoughts.

    Hi Dr Shi,

    We have completed 2nd round of purification that has isolated the fraction specific for unfolded ENaC protein. We will ship you antibody for delivery on Thursday.

    PS. We would recommend to remove glycerol from the lysis buffer because there are 2 detergents present.

    Dear Dr Shi,

    Your custom rabbit pAb project is complete. Please review the attached progress report with ELISA data.

    Both animals reached titer of 1M. Both will give great polyclonal antibodies. If you are interested, we can take your project to rabbit monoclonal selection.

    We will ship purified IgG to you within 5 business days. Please test them and let us know if they work so we can supply you with 1mg of IgG.

    Best regards
    BiCell Scientific Team

"I am really impressed with your approach. We tried multiple times previously to create monoclonal and polyclonal antibodies to claudin-2 and MLCK1. We have had limited success generating polyclonals and no success generating monoclonals. You have generated outstanding monoclonals to both. I look forward to continuing to work with you."

"The polyclonal antibody you generated for KIAA0408 is stunning! KIAA0408 is a novel cilium molecule that has never been studied. So, clearly there will be a lot of demand for it as we have discovered a very interesting finding and the story will be published in a high impact journal. I am strongly inclined to generate monoclonal antibody for this protein too and we should think about patenting it."

"Your ARL13B antibody works beautifully!!! We’re so happy to have a cilia-specific antibody made in rat! I can send you high resolution images to be posted on your website."

"The assay is a homophilic interaction mediated cell adhesion on purified protein (in this case, immobilized purified Pcdhga9 to Pcdhga9 expressed on cell surface). Compared to control, cell adhesion is reduced in the presence of Pcdhga9 monoclonal antibody supernatants!"

"The rabbit hybridoma supernatants of anti-APOBEC3 project are tested positive by ELISA, and we are very happy about it! We previously tried a company, Abclone. Their Project "A" has immune response that is <10,000 titer in antiserum, which would explain why there is no positive mAb after fusion. Their project "B" didn't have any immune response in rabbit."

"We have tested anti mouse T cell antiserum samples from both rabbits you sent to us.

They worked very well! Thank you!"
