The standard kit size of this Mycoplasma Pneumonia DOT ELISA test kit is 48 tests per box; 42 boxes per carton.

To save freight cost, sometimes bulk packing is used, meaning test strip, cassette or multi-test panel is packed in single aluminum pouch; 50 or 100 pouches in one plastic bag; and then plastic bags are packed in cartons along with the unfolded boxes for the test kits. In this way, the customers can easily pack the tests into test kits after receiving the bulk packed goods.

To carry out the assay with a Mycoplasma Pneumoniae IgM DOT-ELISA, Serum should be collected according to the instructions given in the Instruction For Use included in the test kit. After collecting, it is preferable to perform the testing as early as possible; if not viable, the specimen should be stored properly. A general introduction about the collection, and storage of the specimens is given below.

Serum Collection

Collect blood specimen into a red top blood collection tube by vein puncture, which contains no anticoagulants.

Allow the blood to clot, or separate the serum by centrifugation.

Carefully withdraw the serum into a new pre-labeled tube.

Serum Storage Condition

Test specimens as soon as possible after collecting. The specimens can be stored up to 5 days at 2-8°C if not tested immediately. The specimens should be frozen at -20°C for longer time storage. Don’t freeze and thaw the specimens for many times. Prior to testing, bring frozen specimens to room temperature slowly and mix gently. Specimens containing visible particulate matter should be clarified by centrifugation before testing. Do not use samples demonstrating gross lipemia, gross hemolysis or turbidity in order to avoid interference on result interpretation.

Capture Dot ELISA method is used in this Mycoplasma Pneumoniae IgM DOT-ELISA to detect the Mycoplasma Pneumoniae IgM Antibody in human Serum specifically. The introduction of this Capture Dot ELISA testing principle is given blow.

Dot ELISA Capture Method Illustration

IgM-class antibodies usually are connected with primary infections or acute infections, their diagnosis has a special meaning to the clinical diagnosis. In order to avoid false positive caused by the IgG class, capture testing method is often used to detect IgM antibodies.

In capture dot ELISA kit, millipore filtering membrane (usually nitrocellulose,NC) is pre-coated with secondary antibodies directed to human IgM (anti-μ chain) in test dot area. The patient’s serum/plasma sample is added to the membrane, which filtrates through the latter. During the minutes of filtration process, the IgM antibodies, if present, will be captured by the immobilized anti-IgM antibodies, while IgG antibodies will not.

The IgG antibodies will be washed away completely after wash buffer is added.

Then, viral antigens conjugated to horseradish peroxidase (HRP) are added, which will specifically react with the captured viral specific IgM antibodiesn and antigen conjugate will be captured.

After washing to remove unbound conjugates, Chromogen solutions are added to the membrane, then stop solution is added. When HRP present, the colorless chromogens are hydrolyzed to a blue color product at the testing dot area, indicating a positive result.
