Encaleret

(Synonyms: CLTX-305; JTT-305; MK-5442)

Customer Review

Based on 1 Customer Validation

Encaleret (CLTX-305) is an orally active antagonist of the calcium-sensing receptor (CaSR), with an IC₅₀ of 12 nM. Encaleret exerts its effect by inhibiting the excessive activity of functional gain-of-function CaSR variants, and can restore blood calcium levels, promote the secretion of parathyroid hormone, improve magnesium and phosphorus metabolism, and increase urinary calcium excretion. Encaleret can be used in the research of diseases such as osteoporosis and autosomal dominant hypocalcemia type 1.

For research use only. We do not sell to patients.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
