Solute Carrier Family 26 Member 4 (SLC26A4), commonly known as Pendrin, is an anion exchanger mediating chloride-bicarbonate and iodide-chloride exchange across cell membranes. Expressed in the inner ear’s stria vascularis, thyroid follicular cells, and respiratory epithelium, it maintains endolymph ionic balance (critical for auditory/vestibular function) and facilitates iodide uptake for thyroid hormone synthesis.
Mutations in SLC26A4 cause Pendred syndrome (autosomal recessive hearing loss with goiter) and enlarged vestibular aqueduct syndrome. Drug development includes viral vectors for gene therapy (delivering functional SLC26A4), small molecules enhancing residual Pendrin activity, and anion transport modulators—all targeting restored ionic homeostasis in affected tissues to mitigate symptoms.

IHC image of CSB-PA021527LA01HU diluted at 1:500 and staining in paraffin-embedded human melanoma performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
Immunofluorescence staining of HepG2 cells with CSB-PA021527LA01HU at 1:166, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
