  • Autofluorescence Blocking Agent

    Autofluorescence is a major obstacle to using immunofluorescence detection in cells and tissues. There are two major sources of autofluorescence:

    • Native - Caused by such substances as porphyrins, flavins, and lipofuscins
    • Fixation-induced - Caused by formation of fluorescent substances as a result of interaction between aldehyde fixatives with amines
    Autofluorescence, regardless of origin, will obscure specific fluorescent signal when using primary and secondary antibodies conjugated to fluorescent probes. 
     
    FluoMute ready-to-use reagent reduces autofluorescence in cells and tissues, that is simple to add to your immunofluorescence ICC and/or IHC protocols. Treatment with FluoMute does not affect cell morphology and integrity of tissue antigens to be detected with primary antibodies. It is compatible with paraffin-embedded and frozen tissue sections, stem cells, lymphocytes and mammalian cells lines of different origin.

  • ELISA Buffers

    All blocking buffers contain proprietary additives that stabilize the antigenic and functional regions of the coated protein by maintaining the water of hydration during the drying and storage process. These buffers also contain inert additives that block any "sticky" nonspecific binding regions of the adsorbed protein, and any uncoated regions of the polystyrene plate surface. This reduces nonspecific binding of the conjugate and random deposits of sample proteins, thus reducing background noise and increasing the specific signal.

    Buffers also include an antimicrobial agent to prevent bacterial growth during the blocking process (which allows blocking to be done at room temperature) and to extend the useful shelf-life of the plates.

    Energize your ELISA Assays with our Buffers:

    • By saving valuable reagents.
    • By promoting a higher specific signal, less protein may be needed to coat the plate and less of the detection molecules may be needed to generate a signal when this buffer is used.
    • By increasing the shelf-life of your plates. Depending on the activity of the coated protein, plates may be stored at RT or 2°-8°C for several months, or even years under proper conditions.
    • By increasing reproducibility.
    • By using consistent reagents from a reliable source, your ELISAs may become more reproducible.
    • By increasing the signal of the ELISA. If the antibody or antigen is not sticking to the plate, or unwanted proteins are interfering with binding, the plate will have an overall low specific signal. CB1 may foster adsorption and reduce interference.
    • By decreasing background noise. If excess proteins are sticking to the plate, plate will have overall high backgrounds (a high signal overall, but a low specific signal). CB1 may reduce interference.

  • ELISA Assay Diluents
    These assay diluents are proprietary buffer formulations designed to equalize any differences between the sample matrix (serum, plasma, urine, cell culture fluid) and the diluent used to generate the standard curve. These diluents also reduce nonspecific interactions between the sample matrix proteins and the plate surface which translates into lower background noise.  
     
    Assay diluents are pipetted directly onto the plate just prior to adding the samples, and may be used with neat or diluted samples, depending on the characteristics of the sample matrix and the target range of the assay. Since different sample matrices have unique characteristics when run in an ELISA, they must be matched with specific assay diluents. Use of an assay diluent reduces the effects of the sample matrix and variation among samples, without pre-dilution of the samples.
     
    We have 4 proprietary assay diluent formulations for use with sandwich and antigen-down ELISAs:

  • ELISA Sample Diluents
    These unique serum sample diluents are specifically formulated for dilution of animal and bird serum samples in antigen-down ELISA formats. Sample diluents are utilized to dilute serum or antigen samples into the functional range of the assay. 
        
    Due to the finite binding capacity of the coated ELISA plate surface, certain high samples may overload this capacity, thus requiring dilution prior to testing in the assay. Sample diluents can also reduce background noise associated with nonspecific bridging of signal-generating conjugates to the plate surface.  
     
    Hyperimmunized serum samples contain nonspecific IgG antibody that may interfere with the titration signal. Proprietary additives have been incorporated into these diluents that minimize nonspecific binding interactions of the nonspecific IgG in the samples, thus decreasing background noise. 
        

    These sample diluents can be used to titrate rabbit, mouse, goat, and chicken serum samples, along with monoclonal cell culture supernatants.  Antigen samples may also be diluted with sample diluents for evaluation in sandwich ELISA formats.
