Species

Human

Product Overview

Human CCL11 expressed in E.coli

Molecular Mass

8.3 kDa

Size

CAT# CSC-CTK0439-20 (20 μg); CAT# CSC-CTK0439-100 (100 μg)

Expression System

E.coli

Purity

Greater than 98% as determined by SDS-PAGE and RP-HPLC analysis.

Activity

The activity is determined by the chemoattraction of human PBE (peripheral blood eosinophils). It produced a significant increase at a concentration of 100 ng/ml compared to the medium control.

Endotoxin Level

Less than 1 EU/μg.

Formulation

White, lyophilized (freeze-dried) powder. Lyophiliz ed from a sterile-filtered protein solution containing no additives.

Reconstitution

Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.

Storage & Stability

The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rHu Eotaxin should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
