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".
Determined by its ability to increase alkaline phosphatase activity in differentiating MC3T3 cells using a concentration of 0.5-0.7 ug/ml.
Less than 0.1 ng/µg of protein (less than 1EU/µg).
Sterile filtered, lyophilized from 10 mM sodium phosphate, pH 7.6
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. 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.
SPARC Protein, Basement-membrane protein 40 Protein, BM-40 Protein, Cysteine-rich protein Protein, ON Protein, Osteonectin Protein
SPARC (secreted protein acidic and rich in cysteine)/Osteonectin is a matricellular glycoprotein that modulates cellular interactions with the ECM and is expressed in tissues undergoing remodeling. It functions as a de-adhesive protein, as a modulator of growth factor activity, and as a cell-cycle inhibitor. It induces changes in endothelial cell shape via F-actin, coincident with the appearance of intercellular gaps, that provide a paracellular pathway for extravasation of macromolecules.
