  • Product overview

    Abcam’s Albumin Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of albumin levels in urine, saliva, milk, cerebrospinal fluids and cell culture samples.

    An albumin specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently an albumin specific biotinylated detection antibody is added and then followed by washing with wash buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of albumin captured in plate.

  • PlatformMicroplate


  • FunctionSerum albumin, the main protein of plasma, has a good binding capacity for water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. Major zinc transporter in plasma, typically binds about 80% of all plasma zinc.
  • Tissue specificityPlasma.
  • Involvement in diseaseFamilial dysalbuminemic hyperthyroxinemia
  • Sequence similaritiesBelongs to the ALB/AFP/VDB family.
    Contains 3 albumin domains.
  • Post-translational
    Kenitra variant is partially O-glycosylated at Thr-620. It has two new disulfide bonds Cys-600 to Cys-602 and Cys-601 to Cys-606.
    Glycated in diabetic patients.
    Phosphorylation sites are present in the extracellular medium.
    Acetylated on Lys-223 by acetylsalicylic acid.

Thank you for your inquiry. Ab108788 is validated for use with milk samples. The Diluent N does not contain BSA or casein but a BSA like protein. It does not interfere with human albumin measurement or cross react.

The albumin ELISA ab108788 is designed to be able to detect the relatively low amounts (compared to serum and plasma) of albumin in the sample types listed on the datasheet: urine, saliva, milk, cerebrospinal fluid and cell culture supernatants. It wil...

The laboratory has confirmed that the "10X Diluent Concentrate N" does not contain BSA or casein. It contains other proteins that have no cross-reactivity with human albumin.

Yes, we added this diluent to our catalog: Diluent Concentrate (10x) ab172376.

While this kit as not been tested with tissue or cell lysates, in general, a lysis buffer containg a low concentration of triton-X-100 or SP-40 (less than 1 %) will not affect the assay.

The source of the kit ab108788 informed me that they have never tested this kit with horse serum. They have tested it with BSA and they did not see any significant cross-reactivity.

The antibodies used in this kit are optimized for use in kit only. These are not available separately. We have other antibodies available in our catalogue that can be used to develop the assay e.g. ab10241/ ab2406, ab117455
