Using a Checkmark reader performance verification kit the iMark and xMark can be validated to ensure reliability and precision of optical density measurements in order to comply with regulatory requirements.

Immunoenzymatic assays are performed in quadruplicates with the internal control sera, according to the instructions provided in the kits. Dilution buffer (TBS-Tween) is used as a blank. Absorbances are measured at 405 nm with a Bio-Rad iMark microplate reader.

Bio-Rad's microplate readers can be utilized to their full potential with Microplate Manager software. This comprehensive software package allows powerful, versatile colorimetric and turbidimetric analyses, as well as report analysis for raw data, absorbance, limit, matrix, normalization, and curve fit. Microplate Manager software expands your range of data analysis options to include kinetics and screening, and adds the functionality of flexible template creation for any microplate format up to 1,536 wells.

The iMark Microplate Reader has a built-in USB interface. This allows external computers to control theinstrument. When an external computer is in control of the microplate reader, the printer and the membrane keys,except for the Start/Stop and Open/Close keys, are automatically deactivated, and the LCD display appears asbelow.The reader will remain in remote control mode until it is released or until the Start/Stop key is pressed on thereader.

Custom filters between 400 and 750 nm may be ordered. Corresponding catalog numbers can be found onbio-rad, or you can order by specifying the wavelength and the model number of the reader.Checkmark Absorbance Reader Performance Validation Kit (catalog item 168-6940) consists of a plate withabsorbance standards and software to calculate the accuracy and precision of the iMark Microplate AbsorbanceReader.

The iMark Microplate Reader has on-board software that allows the user to set the plate reading and data analysisconditions, to save these settings as a test protocol, to read a microplate under this protocol, and to print reportsfrom the built-in printer. The software communicates through the 4-line, 20-character LCD and is controlledthrough the instrument's membrane keypad.The software has three different protocol types: End-point analysis, Kinetic analysis, and Checkmark validation.The Checkmark validation function is used only by the administrator to verify quality control.The display shows the current mode. The user can choose between these protocol types, or can press the MemoryRecall key to use the current protocol type.

The Microplate Reader uses Beer's Law to calculate the absorbance value of each well. Beer's Law states thatabsorbance is equal to the log10 of the ratio of the baseline measurement intensity (Io) to the samplemeasurement intensity (I). Beer's Law: Absorbance = Log10 (Io/I)Before measuring the plate, the reader takes a reading for all eight photodiode channels. These values arerecorded as the baseline measurement (Io) values for each channel, respectively. The reader then records thesample measurement (I) value for each well, and calculates the absorbance using these values.Channel-to-channel error is significantly reduced because the Io value for a given channel is used only indetermining the absorbance of the wells of that channel.

The iMark Microplate Reader requires a user login with password. This security feature helps to prevent anyunwarranted modifications to the analysis conditions/protocols and data stored in the instrument, and identifiesthe operator on reports. The reader has two user settings, the Administrator and the Common user. Each user levelhas its own security password.

The battery back-up provides memory even after the reader is turned off.The following information will be saved in the memory until new reading parameters are set by the user or a newplate is read by the instrument. Note that if a run is aborted before it is finished, all the previous plate reading dataremain in memory and none of the data from the aborted reading is stored. - The ten latest sets of End-point protocol plate reading results - The two latest sets of Kinetic plate reading results (max. 30 series of readings for each Kinetic Protocol) - 64 End-point Protocol settings and 2 Kinetic Protocol settings - A set of Checkmark reference data and the one latest set of Checkmark reading result - A set of standard curve data for the storage of standard curves and graphs - Eight wavelength values for filters - Laboratory name - Two security passwords (for the Administrator and the Common user) - Instrument serial numberIn addition to the battery back-up memory, the instrument has a small amount of non-volatile memory to keep thesystem information after the battery is dead. The serial number is stored in this memory. The average battery lifeis 5 years.

The quantitative osteogenic ability of each group to induce osteoblast activity was compared by evaluating serum OCN levels using an OCN ELISA kit (Novus, CA, USA). All standards and samples were analyzed using an iMark microplate reader (Bio-Rad, CA, 274 USA) at a wavelength of 450 nm}

We used an indirect ELISA to test for the presence of IgY to Avipoxvirus (Ha et al. 2013). To complete the assays, we coated a 96-well flat-bottomed microplate with avian pox antigen (purified from the Zoetis Chick-N-Pox TC Fowl Pox Vaccine, Zoetis, Inc., Kalamazoo, MI U.S.A.). The purified antigen was diluted to a final concentration of 0.2 g/ml in coating buffer (Bethyl Laboratories, Inc., Montgomery, TX U.S.A.). For the secondary antibody, we used HRP-conjugated goat anti-bird IgY from Bethyl Laboratories. We determined the absorbance of each sample in a BioRad iMark microplate reader (BioRad Laboratories, Inc., Hercules, CA U.S.A.) at 450 nm. We divided the optical density (OD) of each sample by the average OD for the negative controls, and all samples with values greater than or equal to that of the positive control (the lowest positive/negative for a positive control = 2.21) were considered positive for the antibodies. 2351a5e196
