EXBIO Antibodies Product Data Sheet

1P-195-T025

Monoclonal Antibody to CD122
Phycoerythrin (PE) conjugated (25 tests)

Clone: TU27
Isotype: Mouse IgG1
Specificity: The mouse monoclonal antibody TU27 recognizes CD122 (IL-2R beta), a 70-75 kDa type I transmembrane glycoprotein constitutively expressed by NK cells and a T cell subset, and upregulated upon activation.
HLDA V; WS Code C050
Regulatory Status: RUO
Immunogen: TL-Mor cell line
Species Reactivity: Human
Preparation: The purified antibody is conjugated with R-Phycoerythrin (PE) under optimum conditions. The conjugate is purified by size-exclusion chromatography and adjusted for direct use. No reconstitution is necessary.
Storage Buffer: The reagent is provided in stabilizing phosphate buffered saline (PBS) solution containing 15mM sodium azide.
Storage / Stability: Store in the dark at 2-8░C. Do not freeze. Avoid prolonged exposure to light. Do not use after expiration date stamped on vial label.
Usage: The reagent is designed for Flow Cytometry analysis of human blood cells using 10 μl reagent / 100 μl of whole blood or 106 cells in a suspension.
The content of a vial (0.25 ml) is sufficient for 25 tests.
Expiration: See vial label
Lot Number: See vial label
Background: CD122 (IL-2/IL-15R beta) constitutes together with CD132 (common gamma chain) and with CD25 (IL-2/IL15R alpha) the intermediate (CD122+CD132) and the high affinity (CD122+CD132+CD25) IL-2 and IL-15 receptor complex. CD122 is expressed on NK cells and lymphocytes, but at low level, unless the cell is activated. The cytoplasmic part of CD122 binds to Src-family and Jak-family kinases. The biological effect of CD122 ligation depends on whether IL-2 or IL-15 is bound to the receptor complex.
