  • Western blot analysis of extracts from Raji(lane 2(20μg)) or (lane 4(40μg)) using CD19 (HY-P80446) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (1/10,000) was used for 1 hour at room temperature.

  • Immunocytochemistry analysis of Raji cells labeling CD19 with CD19 Antibody (HY-P80446) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with CD19 Antibody (HY-P80446) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L(HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

  • Immunocytochemistry analysis of Ramos cells labeling CD19 with CD19 Antibody (HY-P80446) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with CD19 Antibody (HY-P80446)at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L(HY-P8002,Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

  • Flow cytometric analysis of 1X10^6 Raji cells labeling CD19 Antibody (HY-P80446, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1μg/mL dilution for an hour at 4℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L (HY-P8002) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Rabbit IgG Isotype Control (HY-P80879, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).

背景
功能:在 B 淋巴细胞上作为 B 细胞抗原受体复合物 (BCR) 的辅助受体发挥作用 (PubMed:29523808)。降低下游信号通路激活的阈值,并触发 B 细胞对抗原的应答 (PubMed:1373518, PubMed:16672701, PubMed:2463100)。激活导致磷脂酰肌醇 3-激酶活化和细胞内 Ca2?储存动员的信号通路 (PubMed:12387743, PubMed:16672701, PubMed:9317126, PubMed:9382888)。在骨髓中 B 细胞分化的早期步骤中并非必需 (PubMed:9317126)。是 B-1 细胞正常分化所必需的 (基于相似性)。正常 B 细胞分化和增殖以应对抗原刺激是必需的 (PubMed:1373518, PubMed:2463100)。维持正常血清免疫球蛋白水平以及在抗原刺激下产生高亲和力抗体也是必需的 (PubMed:12387743, PubMed:16672701, PubMed:9317126)。
亚细胞定位:细胞膜;单次跨膜 I 型膜蛋白;膜筏;单次跨膜 I 型膜蛋白
表达水平:
组织特异性:在淋巴结边缘区和生发中心 B 细胞中检测到 (PubMed:2463100) 。在血液 B 细胞中检测到 (蛋白质水平) (PubMed:16672701,PubMed:2463100) 。
异构体 & 翻译后修饰:P15391 有两种异构体:P15391-1:61128 Da (预测值);P15391-2:61200 Da (预测值)。
B 细胞活化后,P15391 在酪氨酸残基上发生磷酸化 (PubMed:10706702, PubMed:12387743, PubMed:7684160, PubMed:7687539)。LYN 可磷酸化 P15391 的酪氨酸残基 (PubMed:7687428)。B 细胞受体活化后,酪氨酸残基依次发生磷酸化。Tyr-531 的磷酸化极其迅速,随后是 Tyr-409 的磷酸化。相比之下,Tyr-500 的磷酸化速度较慢且持续时间较短,很快恢复到基础水平 (基于相似性)。
亚基:与 CR2/CD21 相互作用 (PubMed:1702139)。是成熟 B 细胞膜上由 CD19、CR2/CD21、CD81 和 IFITM1/CD225 组成的复合物的组成部分 (PubMed:1383329)。直接与 CD81 相互作用 (通过其第二个胞外结构域);这种相互作用在内质网/前高尔基体区室的生物合成早期启动,对于活化 B 细胞表面 CD19 受体的转运和区室化至关重要 (PubMed:16449649)。与 VAV 相互作用 (PubMed:10706702)。当 Tyr-348 和/或 Tyr-378 位点磷酸化时,与 GRB2 和 SOS 相互作用。当 Tyr-409 位点磷酸化时,与 PLCG2 相互作用 (PubMed:10706702)。与 LYN 相互作用 (PubMed:7687428)。酪氨酸磷酸化后,与磷脂酰肌醇 3-激酶 (PIK3R1 或 PIK3R2) 的调节亚基 p85 相互作用 (PubMed:7684160)。与 GRB2 相互作用 (PubMed:29523808)。

  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
