Test principle:
This assay employs a two-site sandwich ELISA to quantitate FIS1 in samples. An antibody specific for FIS1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyFIS1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for FIS1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of FIS1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:
The balance between fission and fusion regulates the morphology of mitochondria. TTC11 is a component of a mitochondrial complex that promotes mitochondrial fission. The deduced 152-amino acid protein contains a central leucine zipper, a coiled-coil region, and a C-terminal transmembrane domain. It also contains a region showing high interspecies homology and a putative tetratricopeptide repeat. Immunocytochemical analysis of HeLa cells detected endogenous FIS1 expression in mitochondria. Protease treatment indicated that FIS1 is expressed at the outer mitochondrial membrane. Transfection of a C-terminal truncated FIS1 resulted in cytoplasmic expression, indicating that the C terminus is required for mitochondrial localization.

Specificity:
This assay has high sensitivity and excellent specificity for detection of Human FIS1. No significant cross-reactivity or interference between Human FIS1 and analogues was observed.
Recovery:
Matrices listed below were spiked with certain level of recombinant Human FIS1 and the recovery rates were calculated by comparing the measured value to the expected amount of Human FIS1 in samples.

Precision:
Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision. Inter-assay Precision (Precision between assays) Three samples of known concentration were tested in forty separate assays to assess inter-assay precision. CV (%) = SD/meanX100 Intra-Assay: CV<8% Inter-Assay: CV<12%
Linearity:
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Human FIS1 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Stability:
The stability of ELISA 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. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
Sample collection and storage:
Serum: Use a serum separator tube (SST) and allow samples to clot for two hours at room temperature or overnight at 2 - 8°C before centrifugation for 15 minutes at 1000 × g. Remove serum and assay immediately or aliquot and store samples at ≤ -20°C. Avoid repeated freeze-thaw cycles. Plasma: Collect plasma using EDTA, or heparin as an anticoagulant. Centrifuge for 15 minutes at 1000 × g at 2 - 8°C within 30 minutes of collection. Assay immediately or aliquot and store samples at ≤ -20°C. Avoid repeated freeze-thaw cycles. Other biological fluids: Centrifuge samples for 20 minutes at 1000 × g. Remove particulates and assay immediately or store samples in aliquot at -20°C or -80°C. Avoid repeated freeze/thaw cycles.
Kits storage instructions:
Store at 2-8°C. Please refer to Instruction Manual.
