MS4A1
MS4A1基因編碼CD20蛋白，該抗原為一種疏水性4次跨膜蛋白，分子量大約為35kDa。CD20也叫B淋巴細胞表面抗原B1、Bp35、白細胞表面抗原Leu-16等等。CD20只在B淋巴細胞上表達，參與調節B細胞活化和增殖，作為鈣離子通道發揮作用。除在正常B細胞中表達外，CD20還在B細胞來源的淋巴瘤、白血病等的腫瘤細胞表達，以及涉及免疫疾病和炎癥疾病的B細胞中表達，所以CD20抗原成為淋巴癌、白血病和某些自體免疫等疾病治療的目標靶點。目前，針對這些疾病的CD20治療主要有三種方式，包括抗CD20單克隆抗體、CAR-T和雙特異性抗體。自1997年全球首款抗CD20單抗——羅氏的利妥昔單抗獲批以來，全球已經批準多款抗CD20單抗。相關數據統計顯示，目前有高達90多種針對CD20的生物制劑處于臨床開發階段。
CUSABIO-哺乳包膜VLPs平臺成功開發MS4A1全長膜蛋白（4次跨膜），展示了完整生物活性。

● MS4A1 Recombinant Monoclonal Antibody CSB-RA015007MA4HU
驗證數據
IHC image of CSB-RA015007MA4HU diluted at 1:200 and staining in paraffin-embedded human tonsil tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-Mouse IgG labeled by HRP and visualized using 0.05% DAB
Immunofluorescence staining of Hela cell with CSB-RA015007MA4HU at 1:150, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Mouse IgG(H+L)
Immunofluorescence staining of MCF7 cell with CSB-RA015007MA4HU at 1:150, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Mouse IgG (H+L)
