Purified Mouse Anti-Human Endosialin (CD248)
Purified Mouse Anti-Human Endosialin (CD248)

TOP ROW: Immunohistochemical analysis of Endosialin (CD248) in human tonsil. Following antigen retrieval with BD Retrievagen A Buffer (Cat. No. 550524), the formalin-fixed paraffin-embedded sections of human tomsil were stained with either Purified Mouse IgG1 κ Isotype Control (Cat. No.550878; Left Image) or Purified Mouse Anti-Human Endosialin (CD248) (Right Image). A three-step staining procedure that employs Biotin Goat Anti-Mouse Ig (Cat. No. 550337), Streptavidin HRP (Cat. No. 550946), and the DAB Substrate Kit (Cat. No. 550880) was used to develop the primary staining reagents. As shown in the right image, the CD248-specific antibody primarily stained stromal fibroblasts. Original magnification: 40×.

BOTTOM LEFT: Flow cytometric analysis of human Endosialin (CD248) on human palatal mesenchyme cells. HEPM cells (ATTC, CRL-1486) were surface stained with either Purified Mouse IgG1, κ Isotype Control (Cat. No. 554121, dotted histogram) or Purified Mouse Anti-Human Endosialin (CD248)  (solid line histogram). The second-step reagent was PE Goat Anti-Mouse Ig (Multiple Adsorption, Cat# 550589). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of viable cells. Flow cytometry was performed using a BD FACSCanto™ II Flow Cytometer System.

BOTTOM RIGHT: Western blot analysis of human CD248 in human palatal mesenchyme cells. Lysates of HEPM cells (ATTC, CRL-1486) were prepared for electrophoresis (SDS-PAGE) in a 2D Tris-Glycine polyacrylamide gel. The proteins were transferred to PVDF membranes and then probed with 1 (lane 1), 0.5 (lane 2), and 0.25 (lane 3) µg/mL of Purified Mouse Anti-Human Endosialin (CD248). Specific staining was detected with HRP Goat Anti-Mouse Ig (Cat No 554002).

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  5. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

B1/35

The B1/35 monoclonal antibody specifically binds to CD248 which is also known as Endosialin, Tumor endothelial marker 1 (TEM1), and CD164 sialomucin-like 1 (CD164L1). CD248 is a heavily glycosylated, single-pass type I transmembrane protein. CD248 belongs to the Group XIV C-Type lectin family that includes CD93 and CD141/thrombomodulin. It is expressed on pericytes and stromal fibroblasts. Although the exact functions of CD248 remain to be determined, its expression is associated with angiogenesis and lymphoid tissue organization during development, as well as, with postnatal inflammation and tumor development and growth.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
