Product Details
Down Arrow Up Arrow

BD Pharmingen™
Mouse (QC Testing)
Rat IgG2a
T cell clone supernatant
ELISA (Routinely Tested), Neutralization (Tested During Development), Western blot (Reported)
1.0 mg/ml
No azide/low endotoxin: Aqueous buffered solution containing protein stabilizer, no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.

Preparation And Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. This preparation contains no preservatives, thus it should be handled under aseptic conditions.

Recommended Assay Procedures

Western Blot:  Purified NA/LE Rat Anti-Mouse IL-2 has been reported to be useful for Western blotting.  A concentration of 1-5 µg/mL (in conjunction with an AKP-conjugated goat anti-rat Ig secondary antibody) has been reported to enable detection of  ≤ 100 ng/lane of recombinant mouse IL-2 (Cat. No. 550069) under reducing conditions.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.

Antibody Details
Down Arrow Up Arrow

The S4B6 antibody reacts with mouse interleukin-2 (IL-2). The immunogen used to generate the S4B6 hyridoma was a T cell clone supernatant. This is a neutralizing antibody.

NA/LE refers to the culture and purification methods and buffer used to produce purified antibodies with no azide and low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.NA/LE are perfectly suited to be used in culture or in vivo (for nonhuman studies) for functional assays — blocking, neutralizing, activation or depletion — where the presence of azide may damage cells or exogenous endotoxin may signal or activate cells.
