||1 mg/ml in PBS (after reconstitution).
||Lyophilized- store at 4°C. After reconstitution, if not intended for use within a month, aliquot and store at -20°C.
||Reconstitute with 0.5 ml of H20. Mix gently, wash the sides of the vial and wait 30-60 seconds before use.
|Stability / Shelf Life
||Two years lyophilized, 1month in solution at 4°C.
||By direct ELISA, 1:10,000 dilution will yield 0.4 O.D using alkaline phosphatase conjugated rabbit anti-mouse Ig (Jackson Laboratories). 1:50 dilution will block 70-80% of CTLL proliferative response to 50 units of r.human IL-2.
||A certain degree of functional cross reactivity with murine IL-2 was reported by some investigators.
