Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".
Purified / Lyophilized / Biologically Active / Endotoxin Level: Less than 0.1 ng/µg of protein.
CCL19 / MIP3-Beta
Greater than 98% by SDS-PAGE and HPLC
Determined by its ability to chemoattract human mature dendritic cells using a concentration range of 10.0-100.0 ng/ml.
Less than 0.1 ng/µg of protein (less than 1EU/µg).
Sterile filtered, lyophilized with no additives.
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
If lyophilized, can be stored for 1 month at room temperature, 6 months at 4°C, or through the expiration date at -20°C to -80°C. Once reconstituted per the supplied instructions, can be stored for 3 months at -20°C to -80°C, or for 1 week at 2°C to 8°C. Avoid repeat freeze-thaw cycles.
May play a role not only in inflammatory and immunological responses but also in normal lymphocyte recirculation and homing. May play an important role in trafficking of T-cells in thymus, and T-cell and B-cell migration to secondary lymphoid organs. Binds to chemokine receptor CCR7. Recombinant CCL19 shows potent chemotactic activity for T-cells and B-cells but not for granulocytes and monocytes.
