Biotinylated Human GUCY2C (C-6

Biotinylated Human GUCY2C (C-6His-Avi) (CY93)

产品说明(Description)

Biotinylated Recombinant Human Guanylyl Cyclase C is produced by our Mammalian expression system and the target gene encoding Ser24-Gln430  is expressed with a 6His tag and a Avi tag at the C-terminus.

Accession #: P25092

Known as: Heat-stable enterotoxin receptor; GUCY2C; STA receptor; hSTAR; Guanylyl cyclase C; GC-C; Intestinal guanylate cyclase; GUC2C; STAR

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制(Quality Control)

Purity:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

Biotin:Protein Ratio  The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

 

复溶(Reconstitution)

Always centrifuge tubes before opening. Do not mix by vortex or pipetting. 

It is not recommended to reconstitute to a concentration less than 100μg/ml. 

Dissolve the lyophilized protein in distilled water.

Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. 

Reconstituted protein solution can be stored at 4-7°C for 2-7 days.  

Aliquots of reconstituted samples are stable at < -20°C for 3 months.

 

背景(Background)

GUCY2C (Guanylyl Cyclase C), also known as heat-stable enterotoxin receptor, is a type  I transmembrane protein of the guanylate cyclase (gc) family. GUCY2C cell surface expression is confined to luminal surfaces of the intestinal epithelium and a subset of hypothalamic neurons. The inaccessibility of GUCY2C in the apical membranes of polarized epithelial tissue, due to subcellular restriction of GUCY2C, creates a therapeutic opportunity to target metastatic lesions of colorectal origin which have lost apicalbasolateral polarization without concomitant intestinal toxicity. And that CAR-T cells targeting murine GUCY2C were effective against colorectal cancer metastatic to lung in the absence of intestinal toxicities. Human GUCY2C-targeted CAR that could potentially be employed in patients with GUCY2C-expressing gastrointestinal malignancies.
