|Description||Sandwich High Sensitivity ELISA kit for Quantitative Detection of Human VEGF|
|Cite This Product||Human VEGF PicoKine™ ELISA Kit (Boster Biological Technology, Pleasanton CA, USA, Catalog # EK0539)|
*Our Boster Guarantee covers the use of this product in the above tested applications.
**For positive and negative control design, consult "Tissue specificity" under Protein Target Info.
|Immunogen||Expression system for standard: sf21,A27-R191|
|Cross Reactivity||There is no detectable cross-reactivity with other relevant proteins.|
*Sensitivity, or Lower Limit of Detection (LLD), is the minimum level of target protein the ELISA assay can detect. We measure 20 blank wells and if the O.D. value is 2 standard deviations higher than the blanks' average O.D. the sample can be deemed positive.
*This assay range is determined using common samples. For samples with low target protein concentrations, users can adjust the standard curve to extend the lower limit of assay range.
|Sample Type||cell culture supernates, serum and plasma(heparin, EDTA, citrate).
*The above listed samples are the ones valided with the assay. If you do not see your sample of interest listed, as long as there is enough level of target protein present in the sample, this Picokine™ ELISA kit should detect it.
**For protocol and tips regarding preparing your sample of interest, please check our ELISA sample preparation guide.

Material Required But Not Provided
- 1. Microplate reader in standard size.
- 2. Automated plate washer.

- 4. Clean tubes and Eppendorf tubes.
- 5. Washing buffer (neutral PBS or TBS).
- Preparation of 0.01M TBS: Add 1.2g Tris, 8.5g Nacl; 450μl of purified acetic acid or 700μl of concentrated hydrochloric acid to 1000ml H2O and adjust pH to 7.2-7.6. Finally, adjust the total volume to 1L.
- Preparation of 0.01 M PBS: Add 8.5g sodium chloride, 1.4g Na2HPO4 and 0.2g NaH2PO4 to 1000ml distilled water and adjust pH to 7.2-7.6. Finally, adjust the total volume to 1L.

You can check the tissue specificity below for information on selecting positive and negative control.
|Protein Name||Vascular endothelial growth factor A|
|Molecular Weight||27042 MW|
|Protein Function||Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. NRP1/Neuropilin-1 binds isoforms VEGF-165 and VEGF-145. Isoform VEGF165B binds to KDR but does not activate downstream signaling pathways, does not activate angiogenesis and inhibits tumor growth. .|
|Tissue Specificity||Isoform VEGF189, isoform VEGF165 and isoform VEGF121 are widely expressed. Isoform VEGF206 and isoform VEGF145 are not widely expressed. A higher level expression seen in pituitary tumors as compared to the pituitary gland. .|
|Sequence Similarities||Belongs to the PDGF/VEGF growth factor family.|
|Subcellular Localization||Secreted . VEGF121 is acidic and freely secreted. VEGF165 is more basic, has heparin-binding properties and, although a signicant proportion remains cell-associated, most is freely secreted. VEGF189 is very basic, it is cell-associated after secretion and is bound avidly by heparin and the extracellular matrix, although it may be released as a soluble form by heparin, heparinase or plasmin.|

Typical Data Obtained from Human VEGF PicoKine™ ELISA Kit
(TMB reaction incubate at 37°C for 15-20min)
*The typical data is obtained from Boster's internal QC result and for reference only. It may differ from the lab test results of the end users. It is more important that the user's lab test results reflect the same linearity demonstrated in the typical data than achieving exactly the same O.D. values.
