    • Relevance

      Phycoerythrin is one of a series of fluorescent pigments known as phycobiliproteins, which are produced by red and blue green algae. It occurs in more than one form, and has found application in immunology and diagnostic medicine. B and R Phycoerythrins provide superior labeling compared to fluorescein and rhodamine, and are used for labeling antibodies, usually monoclonals. These dyes may also be coupled to enzymes and other proteins, nucleic acids, polypeptide hormones, drugs, etc. Since phycoerythrins absorb light maximally between 450 and 650nm they fill the need for an intense fluorescent dye in the longer wavelengths of the visible spectrum, thereby avoiding interference from naturally fluorescing biological substances. R Phycoerythrin (240 kDa) is a labile molecule that may dissociate into components upon exposure to reducing or denaturing agents.
    • Cellular localization

      Plastid; chloroplast; chloroplast thylakoid lumen. Periphery of the rods of the phycobilisome.
    • Alternative names

      • R phycoerythrin alpha subunit antibody

    Thank you for sending this information.

    I've found the order information and looked up the lot number, so this is very helpfulfor our internal investigation into the problem with this antibody. You should be receiving the new vial of ab34727 tomorrow, so please keep me updated about the results using this replacement.

    I apologize again for all of the inconvenience, but please let me know if there is anything else that we can do for you.

    Thanks for your reply.

    Please take your time, it's no problem. Weare preparing new aliquots of the antibody and will be sending you another vial on the order ***. I expect this to arrive late next week.

    I apologize again for the inconvenience and for the delay, but please keep me updated about how this new antibody works for you, and let me know if there is anything else you might need from us.

    Thank you for your reply and for keeping me udpated.

    I'm sorry for the delay, but all of our shipment-ready stock does contain the orange precipitate. I'm currently working with our supply chain to get some vials without this problem and hope to resolve this promptly. I realize that your work is being held up, and I again apologize for this.

    In the meantime, could you forward me some additional details about the assay that you're performing? I didn't realize that you had previously used this product successfully, and I just want to make sure that the problem is due directly to the precipitate and not to a different quality issue of the current lot.

    I look forward to hearing from you. Please let me know if you have any questions or if there is anything else that we can do for you.

    Thanks for keeping me updated, and I apologize that there have been so many problems with this antibody.

    I am checking with the lab to see if there's another lotto send, and I will be happy to send a vial if so.

    I didn't realize when we spoke that you've used a different vial of this antibody last week and it worked in your assay. When was the working vial ordered, and what lot is it from? For our records, could you tell me what kind of assay you're performing?

    I will be back in touch tomorrow once I hear from the lab. Please feel free to give me a call if you'd like to speak to me or send a reply to this email if you have any further questions or need anything else from me.

    Thank you for your call today and for sending the images, and I apologize for the trouble with this antibody.

    I just left a voicemail for you, but I wanted to be in touch via email as well. The scientists in the lab did say that they expect the antibody to perform as usual, and the precipitate is just from the HRP conjugation. I inspected the last vial that we have in stock, and it also contains the orange pellet, so if the antibody does not give the expected results, I will send a free of charge vial from a new lot.

    Please keep me updated about the results with this antibody, and let me know if you have any questions or if there is anything else that we can do for you.
