- 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 RBP4/Retinol Binding Protein 4 PicoKine™ ELISA Kit
(TMB reaction incubate at 37°C for 25-30min)
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 Function||Delivers retinol from the liver stores to the peripheral tissues. In plasma, the RBP-retinol complex interacts with transthyretin, this prevents its loss by filtration through the kidney glomeruli.|
|Background||Retinol binding protein 4, plasma, also known as RBP4, belongs to the lipocalin family and is the specific carrier for retinol(vitamin A alcohol) in the blood. It is protein that in humans is encoded by the RBP4 gene. RBP4 gene resides just centromeric of the cluster of CYP2C genes on 10q24. The mouse Rbp4 locus is closely linked and just proximal to the locus for phenobarbital-inducible cytochrome P450-2c(Cyp-2c) at the distal end of chromosome 19. It delivers retinol from the liver stores to the peripheral tissues. In plasma, the RBP-retinol complex interacts with transthyretin, which prevents its loss by filtration through the kidney glomeruli. A deficiency of vitamin A blocks secretion of the binding protein posttranslationally and results in defective delivery and supply to the epidermal cells. The standard used in this kit is recombinant protein, with E19-L201 aa sequence, the molecular weight is 22kda.|
