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 TFF3/Itf 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 Name||Trefoil factor 3|
|Tissue Specificity||Expressed in goblet cells of the intestines and colon (at protein level). Expressed by goblet cells of small and large intestinal epithelia and also by the uterus. Also expressed in the hypothalamus where it is detected in paraventricular, periventricular and supraoptic nuclei (at protein level). .|

|Molecular Weight||8641 MW|
*if product is indicated to react with multiple species, protein info is based on the human gene.
|Protein Function||Involved in the maintenance and repair of the intestinal mucosa. Promotes the mobility of epithelial cells in healing processes (motogen). .|
|Background||Trefoil factor 3 is a protein that in humans is encoded by the TFF3 gene. It is mapped to 21q22.3. Members of the trefoil family can interact with mucins and have an influence on mucus viscosity. They also promote migration of epithelial cells, are linked to antiapoptosis, induce cell scattering, trigger chemotaxis, and participate in immune responses. This gene is a marker of columnar epithelium and is expressed in a variety of tissues including goblet cells of the intestines and colon. It has been found that TFF3 is the most highly upregulated gene in 19 poorly differentiated endometrioid endometrial carcinomas (G3-EECs) compared with normal endometrium biopsies.|
