Purpose This product is optimised for use with FIX&PERM®.
Brand FIX&PERM®
Clone VI-AP
Isotype IgG1
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.
Characteristics Mildly fixes cells, preserving their flow cytometric scatter characteristics
Allows simultaneous characterisation of both intracellular and cell surface markers
Rapid technique - whole procedure can be carried out in less than one hour, ready
for immediate analysis or storage for 24 hours
Stringent QC procedures - the quality of each lot is determined using well-defined
blood samples and subsequent comparison of scatter characteristics of obtained
leukocyte populations, ensuring consistent and reliable results lot after lot
A range of intracellular antibodies with optimised protocols for use with FIX&PERM®
FIX&PERM® is a simple procedure making use of two reagents. Reagent A gently fixes cells, while Reagent B permeabilizes them. The specific formulations reduce background and allow simultaneous addition of permeabilization medium and fluorochrome labelled antibodies, allowing staining of intracellular structures such as cytoplasmic or nuclear enzymes, oncoproteins, cytokines, immunoglobulins, etc.
Purification Purified by Affinity Chromatography
Research Area Secondary Antibodies
Application Notes Direct Immunofluorescence (Staining Procedure) fluorochrome labeled antibodies are designed for use with either whole blood or isolated mononuclear cell (MNC) preparations. Proposed staining procedure for whole blood in short: - For each sample add 50 µL of EDTA anti-coagulated blood to a 3-5 mL tube - Add 20 µL of the appropriate monoclonal antibody conjugate - Incubate the tube for 15 minutes at 4 °C or at room temperature in the dark - Add 100 µL NM-LYSE (ABIN1741580) to each tube and incubate for 10 minutes at room temperature - Add 3-4 mL of destilled water and vortex, incubate for 5-10 minutes at room temperature - Centrifuge tube for 5 minutes at 300 g - Aspirate supernatant and resuspend pellet in 0.3 mL of sheath fluid - Analyze immediately or store samples at 2-8 °C in the dark and analyze within 24 hours Proposed staining procedure for MNC in short: - Carefully add 20 µL antibody conjugate and 50-100 µL MNC to the bottom of a tube - Vortex at low speed for 1-2 seconds - Incubate for 15-30 minutes at 2-4 °C or at room temperature - Centrifuge tubes for 5 minutes at 300 g - Remove supernatant, resuspend cells in 2-5 mL of phosphate buffered saline (PBS) and centrifuge cells again for 5 minutes at 300 g - Remove supernatant and resuspend cells in sheath fluid for immediate analysis or resuspend cells in 0.5 mL 1 % formaldehyde and store them at 2-4 °C in the dark. Analyze fixed cells within 24 hours
Comment

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 Reagents. This isotype control IgG1 is suitable as a Negative Control to be used in combination with 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. nm
