Materials Required But Not Provided
- Microplate reader in standard size.
- Automated plate washer.
- Adjustable pipettes and pipette tips. Multichannel pipettes are recommended in the condition of large amount of samples in the detection.
- Clean tubes and Eppendorf tubes.
- 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 H2
- Preparation of 0.01 M PBS: Add 8.5g sodium chloride, 1.4g Na O and adjust pH to 7.2-7.
Typical Data Obtained from Human PLGF PicoKine™ ELISA Kit
(TMB reaction incubate at 37°C for 15-20min)
Intra/Inter Assay Precision
|Intra-Assay Precision||Inter-Assay Precision|
Three samples with differing target protein concentrations were assayed using four different lots to measure the CV% lot to lot variance.
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.
|Lots||Lot1 (pg/ml)||Lot2 (pg/ml)||Lot3 (pg/ml)||Lot4 (pg/ml)||Mean (pg/ml)||Standard Deviation||CV (%)|
*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.
Protein Target Info (Source: Uniprot.org)
|Protein Name||Placenta growth factor|
|Tissue Specificity||While the three isoforms are present in most placental tissues, PlGF-2 is specific to early (8 week) placenta and only PlGF-1 is found in the colon and mammary carcinomas.|
|Alternative Names||Placenta growth factor;PlGF;PGF;PGFL, PLGF;|
|Subcellular Localization||Secreted. The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin.|
|Molecular Weight||24789 MW|
*if product is indicated to react with multiple species, protein info is based on the human gene.
|Protein Function||Growth factor active in angiogenesis and endothelial cell growth, stimulating their proliferation and migration. It binds to the receptor FLT1/VEGFR-1. Isoform PlGF-2 binds NRP1/neuropilin-1 and NRP2/neuropilin-2 in a heparin-dependent manner. Also promotes cell tumor growth. .|
|Background||The protein, also called PGF, is 149 amino acids long and shares 53% identity with the platelet-derived growth factor-like region of human VPF. And the N-glycosylated PLGF protein is secreted into the medium and that it functions as a dimer1. The PLGF gene is mapped to 14q24-q31. There are 3 isoforms of PGF, designated PGF1, PGF2, and PGF3. Only PGF2 is able to bind heparin. Additionally, PGF regulates inter- and intramolecular cross-talk between the VEGF receptor tyrosine kinases FLT1 and FLK12. It also can stimulate angiogenesis and collateral growth in ischemic heart and limb with at least a comparable efficiency to VEGF3.|
