specificity :
This assay has high sensitivity and excellent specificity for detection of rat LIF. No significant cross-reactivity or interference between rat LIF and analogues was observed.
storage stability :
Unopened test kits should be stored at 2 to 8 degree C upon receipt. Please refer to pdf manual for further storage instructions.
other info1 :
Samples: Serum, plasma, bronchoalveolar lavage fluid, tissue homogenates. Assay Type: Sandwich. Detection Range: 0.312 ng/ml -20 ng/ml. Sensitivity: The minimum detectable dose of rat LIF is typically less than 0.078 ng/ml. The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined the mean O.D value of 20 replicates of the zero standard added by their three standard deviations.
other info2 :
Intra-assay Precision: Intra-assay Precision (Precision within an assay): CV%<8%. Three samples of known concentration were tested twenty times on one plate to assess. Inter-assay Precision: Inter-assay Precision (Precision between assays): CV%<10%. Three samples of known concentration were tested in twenty assays to assess.
products description :
Principle of the Assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for LIF has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any LIF present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LIF is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of LIF bound in the initial step. The color development is stopped and the intensity of the color is measured.

ncbi summary :
a secreted cytokine; involved in embryonic stem cell and myeloid cell growth and differentiation and stimulation of bone remodeling [RGD, Feb 2006]
uniprot summary :
Function: LIF has the capacity to induce terminal differentiation in leukemic cells. Its activities include the induction of hematopoietic differentiation in normal and myeloid leukemia cells, the induction of neuronal cell differentiation, and the stimulation of acute-phase protein synthesis in hepatocytes.
