蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 25.6 kDa. The protein migrates as 35-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Conjugate
FITC
Excitation source: 488 nm spectral line, argon-ion laser
Excitation Wavelength: 488 nm
Emission Wavelength: 535 nm
标记（Labeling）
The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with FITC using standard chemical labeling method. The residual FITC is removed by molecular sieve treatment during purification process.
蛋白标记度（FITC:Protein Ratio)
The FITC to protein molar ratio is 2-4.5.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 . Normally trehalose is added as protectant before lyophilization.

电泳（SDS-PAGE）
FITC-Labeled Human CLEC12A, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90%.
活性（Bioactivity）-FACS
2e5 of Anti-CLEC12A CAR-293 cells were stained with 100 μL of 10 μg/mL of FITC-Labeled Human CLEC12A, His Tag (Cat. No. CLA-HF247) and negative control protein respectively. FITC signal was used to evaluate the binding activity (QC tested).
Protocol
背景（Background）
CLEC12A (C-type lectin domain family 12 member A) is also known as CLL1, DCAL2, MICL. Clec12a is an inhibitory receptor for uric acid crystals that regulates inflammation in response to cell death. Cell surface receptor that modulates signaling cascades and mediates tyrosine phosphorylation of target MAP kinases. Evidence of distinct disease propagating stem cells in myelodysplastic syndrome (MDS) has emerged in recent years. The role of CLEC12A in MDS, however, remains to be elucidated. Furthermore, CLEC12A has been proposed as a promising marker of leukaemic stem cells in AML.
