The SSEA-4 (Stage-Specific Embryonic Antigen-4) is a significant glycolipid antigen belonging to the Globo series glycosphingolipids (such as Gb5 and SSEA-3). Its structural characteristic is Neu5Gcα2-3Galβ1-3GalNAcβ1-3Galα1-4Galβ1-4Glcβ1-Cer. It is highly expressed during early embryonic development (e.g., in morula and blastocyst stages) and in pluripotent stem cells (such as human embryonic stem cells, hESCs, and induced pluripotent stem cells, iPSCs), making it a widely used surface marker for pluripotency. Additionally, SSEA-4 is aberrantly expressed in various cancers (e.g., breast cancer, lung cancer, gliomas) and is associated with tumor progression, metastasis, and immune evasion, potentially through the regulation of cell adhesion or signaling pathways (e.g., EGFR/ERK). Notably, since humans lack the enzyme to synthesize its sialic acid component (Neu5Gc), SSEA-4 expression may rely on exogenous uptake or non-canonical biosynthetic pathways. This unique feature also presents a potential therapeutic target for cancer treatment.
流式分析
Flow cytometric analysis of 4% PFA fixed 90% methanol permeabilized NTERA-2 (Human malignant multiple teratoma cells) labelling SSEA4 antibody at 1/500 dilution (0.1 μg) / (Red) compared with a Rabbit monoclonal IgG (Black) Isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti - Rabbit IgG Alexa Fluor® 488 was used as the secondary antibody. Negative control: Raji
免疫细胞化学
ICC shows positive staining in NTERA-2 cells. Anti-SSEA4 antibody was used at 1/500 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue). Counterstain with tubulin (Red).
FAQs
我们一般不推荐客户回收利用抗体。 因为抗体使用之后缓冲体系已经发生改变，不同客户在回收抗体的保存条件上也会有差异，所以抗体回收使用效果无法保证。另外，我们对一批抗体回收验证测试，测试结果显示不同抗体可回收次数不同，一般效价越高的抗体，可重复使用的次数越多，客户可根据实验情况来确定
