  • 产品概述

    Abcam’s IL-4 Rat ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of rat IL-4 in serum, plasma, and cell culture supernatants.

    This assay employs an antibody specific for rat IL-4 coated on a 96-well plate. Standards and samples are pipetted into the wells and IL-4 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-rat IL-4 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of IL-4 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

性能

  • 相关性IL4 is a pleiotropic cytokine produced by activated T cells. It is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of IL4. IL4, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. IL4, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome. Two alternatively spliced transcript variants of IL4 encoding distinct isoforms have been reported.

    regarding IL-4 rat elisa (ab100770) -

    In the protocol (page 7) #6. PREPARATION OF REAGENTS, step 6. says to add diluent B to prepare the detection antibody and step 7 says to add diluent B to dilute HRP. My question is this, should you use d...

    Thank you for contacting us.

    Yes, Assay Diluent A contains sodium azide which inhibits HRP activity. Therefore in this case 1X Assay Diluent B should always be used to prepare the HRP-Streptavidin and detection antibody regardless of the sam...

    Can serum samples be run "neat" (without dilution) in the IL-4 Elisa - ab100770?


    The lab adviced the following:

    While serum and plasma samples maybe run undiluted, we do not usually recommend doing so. The reason is not because Assay Diluent A needs to be present in every sample but that testing undiluted serum/plasma...

    What is the normal amount of rat IL4 in serum?
    What is the normal amount of rat IL6 in serum?
    What is the recommended dilution range?


    I have the following information for you regarding the kits we discussed:


    ab46073:
    We have no data regarding normal values observed with IL-6 and IL-4 in rat but as free circulating cytokines are rather dangerous for living ani...
