A DNA sequence encoding the human TSHR (NP_000360.2) (Gly21-Gly413) was expressed with a His tag at the C-terminus.

A DNA sequence encoding the human CGA (NP_000726.1) (Met 1- Ser 116) was expressed, constructed the plasmid 1; A DNA sequence encoding the human FSHB(NP_000501.1) (Met 1- Glu 129) was fused with the Fc region of human IgG1 at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the human CGA&FSHB heterodimer was purified.

Recombinant Human Stanniocalcin 1/STC Protein was expressed in HEK293. It is a Full length protein.

MagicScript II Reverse Transcriptase is a recombinant M-MuLV reverse transcriptase with reduced RNase H activity and increased thermostability. It can be used to synthesize first strand cDNA at higher temperatures than the wild type M-MuLV. The enzyme is active up to 48°C, providing higher specificity, higher yield of cDNA and more full-length cDNA product up to 12 kb.

Pfu DNA Polymerase is a high-fidelity, thermostable enzyme isolated from Pyrococcus furiosus. Pfu DNA Polymerase possesses 3`→5` exonuclease (proofreading) activity. Base misincorporations that may occur during polymerization are rapidly excised by this proofreading activity. MagicFast Pfu DNA Polymerase has been genetically engineered to enhance the amplification efficiency by fusing DNA binding domains to the Pfu DNA polymerase. MagicFast Pfu DNA Polymerase has the characteristics of high amplification speed (extension ~2 kb/min), high fidelity and strong anti-interference ability. Consequently, MagicFast Pfu DNA Polymerase is recommended for use in PCR and primer extension reactions that require high-fidelity synthesis. MagicFast Pfu DNA Polymerase-generated PCR fragments are blunt-ended.

2019-nCoV Spike S1-RBD IgG&IgM ELISA Kit is an indirect ELISA which can be used for evaluation of anti-SARS-CoV-2 Spike S1-RBD IgG or IgM in serum/ plasma samples. IgG: OD values of samples compared with ones of a weak positive standard (0.008 μg/mL) and a strong positive standard (1 μg/mL). IgM: OD values of samples compared with 2.1 times of the OD value of 0 μg/mL standard. Inter-assay: -‰¤ 10%; Intra-assay: -‰¤ 15%. All reagents and buffers for test are provided complete the test within 1 hours.
