1. INTENDED USE:
Quantitative LC-MS/MS analysis kit for Amino Acids in biological fluids (Plasma &
Serum & Urine & Cerebrospinal Fluid).
2. SUMMARY AND EXPLANATION:

Amino acids are the basic structural units of the proteins. Quantitative analysis of the
amino acids in biological fluids is one of the most important parts of the clinical
diagnosis of patients with inborn errors of amino acid metabolism or monitoring the
healthy people. Amino acid analysis in urine is important for diagnosis of disorders
which are related with renal amino acid transport. Quantitative analysis of amino acids
in plasma is preferred over urine for the diagnosis of aminoacidopathies which cause to
accumulation or the deficiency of amino acids in biological fluids.
Quantitative analysis of the amino acids in biological fluids also has clinical importance
for determining some neurological and endocrinal disorders. LC-MS/MS is an
influential device for the study of disorders related with amino acids. LC-MS/MS
analysis gives results for 47 free amino acids in 20 minutes.
Zivak Quantitative Free Amino Acids LC-MS/MS Analysis Kit was developed for
quantitative detection of free amino acids in human serum, plasma, urine and
cerebrospinal fluid LC-MS/MS is an influential device for the study of metabolic
disorders and LC-MS/MS analysis gives results in 20 minutes with minimal sample
preparation. Main methods and procedures that have been selected are based on EN
ISO 13485 and 98/79/EC.

3. TEST PRINCIPLE:

Free amino acids are extracted from human samples by using an acidic extraction and
deproteinization steps. After the extraction, these amino acids derivatised via reagents.
Then derivatisated amino acids are separated on a reversed phase HPLC column with a
gradient elution and analysed by Tandem Mass spectrometry.

4. WARNING AND PRECAUTIONS:

• For in-vitro diagnostic use only.
• For professional use only.

working with biological fluids. Appropriate bio-safety precautions and disposal
of bio-hazardous wastes should be followed.
• Please check the labels on reagent bottles. Reagents of this kit contain hazardous
material may cause eye and skin irritations.
• It’s recommended to work in a fume hood for your safety as Reagent 2, 3 and 4
are volatile and please avoid inhaling.
5. STORAGE AND STABILITY:

8. PROCEDURE NOTES:

Any inappropriate handling of samples or modification of the test procedure may
influence the results. The indicated pipetting volumes, incubation times, temperatures
and pre-treatment steps have to be performed strictly according to the instructions.
Use calibrated pipettes and devices only.

Once the test has been started, all steps should be completed without interruption.
Make sure that required reagents, materials and devices are prepared ready at the
appropriate time. Leave aside all reagents and specimens to reach room temperature
(18-25 °C) and gently swirl each vial of liquid reagent and sample before use. Mix
reagents without foaming.
Avoid contamination of reagents, pipettes and wells/tubes. Use new disposable plastic
pipette tips for each reagent, standard or specimen. Do not interchange the vial caps.
Always keep vials closed when not been used. Do not re-use wells/tubes or reagents.

Incubation time affects results. All tubes or wells should be handled in the same order
and time sequences.
9. LIMITATIONS OF THE PROCEDURE:

Specimen collection and storage have a significant effect on the test results. Plasma
samples from earlier days must be kept frozen before the analysis. If the urine sample
is not clear, it must be centrifuged before sample preparation.
10. PRE-TEST SET-UP INSTRUCTIONS:

Set-up the Instrument:
• Purge the HPLC pumps with a high flow rate of mobile phase(s). This should be
done by pumping the mobile phase(s) through the system for 2 minutes at a flow rate
of 4.0 ml/min.
• Switch off the pump and connect the column in flow direction.
• Activate the method and allow mobile phase(s) to flow through the column for
15 minutes.
• Make sure the bottle of mobile phase bottle is closed well, otherwise
components of the mobile phase could evaporate; this alters the retention times.
