Bovine Bone Morphogenetic Protein 4 (BMP4) ELISA Kit

Principle of the Assay

The microtiter plate provided in this kit has been pre-coated with an antibody specific to BMP4. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to BMP4. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain BMP4, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of BMP4 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.

Target Information

Growth factor of the TGF-beta superfamily that plays essential roles in many developmental processes, including neurogenesis, vascular development, angiogenesis and osteogenesis (By similarity). Acts in concert with PTHLH/PTHRP to stimulate ductal outgrowth during embryonic mammary development and to inhibit hair follicle induction (By similarity). Initiates the canonical BMP signaling cascade by associating with type I receptor BMPR1A and type II receptor BMPR2. Once all three components are bound together in a complex at the cell surface, BMPR2 phosphorylates and activates BMPR1A. In turn, BMPR1A propagates signal by phosphorylating SMAD1/5/8 that travel to the nucleus and act as activators and repressors of transcription of target genes. Can also signal through non-canonical BMP pathways such as ERK/MAP kinase, PI3K/Akt, or SRC cascades. For example, induces SRC phosphorylation which, in turn, activates VEGFR2, leading to an angiogenic response (By similarity).

Performance Characteristics


Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level BMP4 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle, and high-level BMP4 were tested on 3 different plates, with 8 replicates in each plate.
CV(%) = SD/meanX100

Intra-Assay: CV<10%
Inter-Assay: CV<12%

SENSITIVITY The minimum detectable dose was 0.074ng/mL.
ASSAY RANGE 0.156-10ng/mL
SPECIFICITY This assay has high sensitivity and excellent specificity for the detection of BMP4.
No significant cross-reactivity or interference between BMP4 and analogs was observed.
Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between BMP4 and all analogs, therefore, cross reactivity may still exist.
