Detection of TRA-1-81 antibody in BG01V Human Cells antibody by Flow Cytometry.

Detection of TRA-1-81 in BG01V Human Cells by Flow Cytometry.

BG01V human embryonic stem cells were stained with Mouse Anti-Human TRA-1-81 Monoclonal Antibody (Catalog # MAB8495, filled histogram) or mouse IgM isotype control antibody (open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgM Secondary Antibody (Catalog # F0117).
TRA-1-81 antibody in BG01V Human Embryonic Stem Cells by Immunocytochemistry (ICC).

TRA-1-81 in BG01V Human Embryonic Stem Cells.

TRA-1-81 was detected in immersion fixed BG01V human embryonic stem cells using Mouse Anti-Human TRA-1-81 Monoclonal Antibody (Catalog # MAB8495) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgM Secondary Antibody (red; Catalog # NL019) and counterstained with DAPI (blue). Specific staining was localized to cell membrane. View our protocol for Fluorescent ICC Staining of Stem Cells on Coverslips.

Formulation, Preparation, and Storage

Purification

IgM-specific Affinity-purified from hybridoma culture supernatant

Reconstitution

Reconstitute at 0.5 mg/mL in sterile PBS. For liquid material, refer to CoA for concentration.

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Shipping

Lyophilized product is shipped at ambient temperature. Liquid small pack size (-SP) is shipped with polar packs. Upon receipt, store immediately at the temperature recommended below.

Stability & Storage

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 12 months from date of receipt, -20 to -70 °C as supplied.
  • 1 month, 2 to 8 °C under sterile conditions after reconstitution.
  • 6 months, -20 to -70 °C under sterile conditions after reconstitution.

Calculators

The reconstitution calculator allows you to quickly calculate the volume of a reagent to reconstitute your vial. Simply enter the mass of reagent and the target concentration and the calculator will determine the rest.

Background: TRA-1-81

The TRA-1-81 antibody reacts with a high-molecular-mass carbohydrate epitope on the surface of human embryonal carcinoma (EC), embryonic germ (EG), embryonic stem (ES), and induced pluripotent stem (iPS) cells.  TRA-1-81 is an epitope expressed on podocalyxin, also known as Podocalyxin-Like Protein-1 (PCLP1 or PODXL), a type I transmembrane glycoprotein.
