IgG1 Negative Control, conjugated to FITC

IgG1 Negative Control, conjugated to FITC, IgG1, Clone: VI-AP

Clone: VI-AP

Label: FITC

Background: This ready to use negative control reagent contains purified, fluorescein or phycoerythrin conjugated mouse immunoglobulin molecules of IgG1 isotype, which have been selected on the basis of their binding characteristics: no specific binding to human cell surface or intracellular antigens, same low range of nonspecific binding to human leukocytes as other Nordic-MUbio Reagents. This isotype control IgG1 is suitable as a Negative Control to be used in combination with Nordic-MUbio reagents for the: - Enumeration of Myeloid Cells - Analysis of Myeloid Differentiation Stage - Enumeration of B-cells and Precursors - Enumeration of T-cells and Precursors - Analysis of Leukemia Cells - Analysis of Immunodeficiency StatesThe negative control reagent permits to estimate the degree of non-specific binding of isotype matched immunologbulins to leukocytes via e.g. Fc-receptors. It enables the expert to set flow cytometric parameters accordingly.Results must be put within the context of other diagnostic tests as well as the clinical history of the patient by a certified professional before final interpretation.

Specificity: The clone VI-AP reacts with calf intestine alkaline phosphatase and does not show cross-reactivity with human proteins. The sensitivity of VI-AP mAb is determined by staining well-defined blood samples from representative donors with serial-fold mAb dilutions to obtain a titration curve that allows relating the mAb concentration to the percentage of stained cells and geometric MFI (mean fluorescence intensity). For this purpose, a mAb-concentration range is selected to include both the saturation point (i.e. the mAb dilution expected to bind all epitopes on the target cell) and the detection threshold (i.e. the mAb dilution expected to represent the least amount of mAb needed to detect an identical percentage of cells). In practice, 50 µl of leukocytes containing 10^7 cells/ml are stained with 20 µl mAb of various dilutions to obtain a titration curve and to identify the saturation point and detection threshold. The final concentration of the product is then adjusted to be at least 3-fold above the detection threshold. In addition and to control lot-to-lot variation, the given lot is compared and adjusted to fluorescence standards with defined intensity.

Formulation: 1 microgram per ml in PBS pH 7.2, 1% BSA, 0.05% NaN3

Caution: For professional users only. This reagent contains sodium azide. To avoid the development of hazardous conditions, reagents containing azide should be diluted in running water prior to be discarded. Similar to the work with other biological products, proper handling procedures are recommended.
