簡單介紹：

2019 nCoV/COVID19 Spike protein S1 protein (Recombinant) (His-Tag) (STJP000269)

詳情介紹：

Host:	HEK293
Note:	STRICTLY FOR FURTHER RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS.
Short Description:	Recombinant-2019 nCoV/COVID19 Spike protein S1-His-Tag protein was developed from hek293 and has a target region of His-Tag. For use in research applications.

Conjugation:	Unconjugated
Formulation:	Lyophilised from 0.2 µm filtered PBS solution pH7.4.
Dilution Range:	Spin the vial and reconstite in distilled water to a concentration not less than 0.1 mg/mL. This can then be diluted into other buffers.
Storage Instruction:	The lyophilized protein is stable for at least 1 year from date of receipt at-20°C. NA
Endotoxin:	Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg). NA
Immunoreactivity:	The activity was tested by binding Human ACE2-Fc in functional ELISA assay, the calculated EC50 was determined to be 0.1ug/ml. NA

Immunogen Region:	ECD
Immunogen:	DNA sequence encoding extracellular fragment[16-675] of NCOV Spike S1 [accession# QIC53204.1] including a C terminal polyHis was expressed in HEK cells. NA

Background

Recombinant NCOV S1 encodes the NCOV spike glycoprotein S1 sequence. This molecule has a calculated mass of approximately 76kDa. Recombinant S1 migrates due to glycosylation as an approximately 120 kDa protein under reducing conditions in SDS-PAGE.
