  • 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".

Description: Agonists of the vitamin D receptor are used to suppress parathyroid hormone (PTH) synthesis and secretion in the treatment of hyperparathyroidism associated with renal failure. 22-Oxacalcitriol is an analog of calcitriol that, like calcitriol, is a receptor-active form of vitamin D3 which effectively blocks PTH synthesis. First reported to avoid hypercalcemia, an undesirable side effect of calcitriol, prolonged treatment with 22-oxalcalcitriol can be calcemic in humans. Analogs of calcitriol, including 22-oxacalcitriol, inhibit human keratinocyte proliferation while inducing differentiation and is beneficial in treating psoriasis. 22-Oxacalcitriol also blocks the proliferation while inducing differentiation and apoptosis of certain tumor cells.

Usage Information

22-Oxacalcitriol is supplied as a crystalline solid. A stock solution may be made by dissolving the 22-oxacalcitriol in the solvent of choice. 22-Oxacalcitriol is soluble in ethanol, which should be purged with an inert gas. The solubility of 22-oxacalcitriol in ethanol is approximately 1 mg/ml. It is slightly soluble in acetone, chloroform, and DMSO and insoluble in water.
