Medchemexpress LLC BCA-1/CXCL13 protein, cynomolgus (His tag) | >95.0% | 10 UG
Recombinant cynomolgus CXCL13 (BCA-1) is a His-tagged chemokine produced in E. coli for use in cell-based and biochemical assays. It acts as a B-lymphocyte chemoattractant and is supplied lyophilized with recommended reconstitution and storage instructions. Purity and bioactivity are validated by SDS-PAGE and cell migration assays.
- Recombinant cynomolgus CXCL13 (BCA-1), His-tagged.
- Expressed in E. coli.
- Purity >95.0% by reducing SDS-PAGE.
- Approximate molecular weight 13 kDa under reducing conditions.
- Lyophilized from 10 mM Tris, 250 mM NaCl, pH 8.0.
- Validated chemoattractant activity on Ramos cells (ED50 0.019 μg/mL).
- Store lyophilized at -20°C; aliquot and freeze at -20°C or -80°C after reconstitution.
