Recovery

Matrices listed below were spiked with certain level of Mini Samples Hyaluronic Acid (HA) and the recovery rates were calculated by comparing the measured value to the expected amount of Mini Samples Hyaluronic Acid (HA) in samples.

Matrix	Recovery range (%)	Average(%)
serum(n=5)	90-103	97
EDTA plasma(n=5)	78-89	84
heparin plasma(n=5)	80-97	80

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Mini Samples Hyaluronic Acid (HA) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample	1:2	1:4	1:8	1:16
serum(n=5)	96-104%	80-92%	83-92%	79-98%
EDTA plasma(n=5)	98-105%	90-101%	97-105%	80-94%
heparin plasma(n=5)	82-93%	78-94%	90-104%	80-93%

Precautions

The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Notes

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Mini Samples Hyaluronic Acid (HA) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Mini Samples Hyaluronic Acid (HA) and unlabeled Mini Samples Hyaluronic Acid (HA) (Standards or samples) with the pre-coated antibody specific to Mini Samples Hyaluronic Acid (HA). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Mini Samples Hyaluronic Acid (HA) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Mini Samples Hyaluronic Acid (HA) in the sample.

Antigen	HA
Usage Notes	1. Prepare all reagents, samples and standards; 2. Add 25µL standard or sample to each well. And then add 25?L prepared Detection Reagent A immediately. Shake and mix. Incubate 1 hour at 37°C; 3. Aspirate and wash 3 times; 4. Add 50µL prepared Detection Reagent B. Incubate 30 minutes at 37°C; 5. Aspirate and wash 5 times; 6. Add 50µL Substrate Solution. Incubate 10-20 minutes at 37°C; 7. Add 25µL Stop Solution. Read at 450 nm immediately.

Applications	ELISA
Research Area	Tumor immunity
Precision	Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Mini Samples Hyaluronic Acid (HA) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Mini Samples Hyaluronic Acid (HA) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: C<10% Inter-Assay: C<12%

Storage	4°C for 1 month/ -20°C for long-term(within shelf life)
