  • Function

    Thought to provide a protective, lubricating barrier against particles and infectious agents at mucosal surfaces.
  • Tissue specificity

    Expressed in corneal and conjunctival epithelia (at protein level). Overexpressed in ovarian carcinomas and ovarian low malignant potential (LMP) tumors as compared to the expression in normal ovarian tissue and ovarian adenomas.
  • Sequence similarities

    Contains 2 ANK repeats.
    Contains 56 SEA domains.
  • Domain

    Composed of three domains, a Ser-, Thr-rich N-terminal domain, a repeated domain containing more than 60 partially conserved tandem repeats of 156 amino acids each (AAs 12061-21862) and a C-terminal transmembrane contain domain with a short cytoplasmic tail.
  • Post-translational

    Heavily O-glycosylated; expresses both type 1 and type 2 core glycans.
    Heavily N-glycosylated; expresses primarily high mannose and complex bisecting type N-linked glycans.
    May be phosphorylated. Phosphorylation of the intracellular C-terminal domain may induce proteolytic cleavage and the liberation of the extracellular domain into the extracellular space.
    May contain numerous disulfide bridges. Association of several molecules of the secreted form may occur through interchain disulfide bridges providing an extraordinarily large gel-like matrix in the extracellular space or in the lumen of secretory ducts.
  • Cellular localization

    Cell membrane. Secreted > extracellular space. May be liberated into the extracellular space following the phosphorylation of the intracellular C-terminus which induces the proteolytic cleavage and liberation of the extracellular domain.

Thank you for contacting us.

Following Western blot conditions have been tested with our anti-CA-125 MAbs:

1. CA125 is immobilized on the nitrocellulose membrane for 30 min (400 mA, 25 mM Tris-Hcl, 192 mM Glycin, 0,1% SDS, 20% ethanol) (Deglycosylation of the CA125 is not needed)

2. Blocking by 0.2% casein

3. Incubation with diluted MAbs for 1 hour at + 20°C

4. Washing (PBS-Tween)

5. Incubation with conjugate for 1 hour at + 20°C

6. washing (PBS-Tween)

7. Staining by 0.05 % DAB, H2O2.

Tween is added to buffers in each step.

With crude antigen from cells as sample and MAb X75 a diffuse area on top of the gel around 200 kDa is detected. Unfortunately image is not available.

We have used 6% or 8% gel.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your resposne.

As my colleauge has explained in the previous e-mail, our antibodies and proteins will regrettably not have been tested and guaranteed in the application you are using (i.e. electrical biosensors).

As ELISA is the closest application, I am pleased to recommend some antibodies suitable for this applications, however these will not be covered by our guarantee for electrical biosensors.

CA 15.3 - none

TRU-QUANT - none

CA 27.29 - none

CA125 - ab10033, ab10029, ab19551

CEA (carcinoembryonic antigen) - ab15987, ab4451,

If you need any further assistance in the future, please do not hesitate to contact me.
