(mb HAIN LPA) GENOTYPE, MTBDRsl, ver. 2.0, 1 test, 31796A

KIT composed of 2 separate elements with different storage conditions:

• component 1/2 (cardboard box) to be stored between 2° and 8°C
• component 2/2 (small bag) to be stored at -20°C (deep freeze)

Kit contains sufficient reagents for analysis of 96 samples.

• Substrate Buffer (SUB-D) contains buffer, <1% MgCl₂, <1% NaCl, 96 ml
• Tray, evaluation sheet 4 of each
• Instructions for use, template 1 of each

Kit Component 2 of 2 (store at –20°C)

• Amplification Mix A (AM-A GT MTBDRsl VER 2.0) contains buffer, nucleotides, Taq polymerase, 4x240 µl
• Amplification Mix B (AM-B GT MTBDRsl VER 2.0) contains salts, specific primers, dye, 4x 840 µl

Quality control

In order to control the correct performance of the test and the proper functioning of kit constituents, each strip includes 5 control zones:

• a Conjugate Control zone (CC) to check the binding of the conjugate on the strip and a correct chromogenic reaction
• an Amplification Control zone (AC) to check for a successful amplification reaction
• three Locus Control zones (rpoB, katG, and inhA) checking the optimal sensitivity of the reaction for each of the tested gene loci

A negative control sample for detection of possible contamination events containing water (molecular biology grade) instead of DNA should be part of each test run; the respective test strip should show the bands CC and AC only.

1 kit = 96 tests

Material Required but not Included in the Kit/ see checklist molecular biology Hain

• See: MSF diagnostic packages, MSF, 2023

• It is essential that all materials (such as pipette tips) coming in contact with the reagents are free from DNases.
• Do not interchange or pool Amplification Mixes or membrane strips from different kits unless the lots are identical.
• When handling kit reagents, the following special safety measures must be applied:
• The denaturation Solution (DEN) contains <2% NaOH and is irritating to eyes and skin (R36/38 and S26-37/39-45).
• The Substrate Concentrate (SUB-C) contains dimethyl sulfoxide and is irritating (R36/37/38, S23-26-36).

• Store all constituents from Kit Component 1 between 2 and 8°C.
• Store all constituents from Kit Component 2 at –20°C and keep strictly separated from contaminating DNA.
• Avoid repeated freezing and thawing of AM-A and AM-B; when processing only small sample numbers per run, aliquot AM-A and AM-B.
• Shelf life: 14 to 15 months
• Guaranteed minimum remaining shelf life at delivery: 1/3 of total shelf life
• Do not use the reagents beyond their expiry date.

(Cf Introduction: Thermosensitive products)

• Dispose of unused reagents and waste in accordance with federal, state, and local regulations.
• Discard used pipette tips immediately after use in a container for biohazardous waste.
• Discard all used disposables in a container for biohazardous waste to be incinerated.

Not classified as hazardous: AM-A, AM-B, CON-C, CON-D, HCD, PNM, RIN, STR, Strips, SUB-D, SUB-C, HYB

Denaturation solution:

• Skin irritation, category 2
• Eye irritation, category 2

Conjugate buffers (CON-C and CON-D) contain biological material and therefore must be considered as potentially infectious
