  • General notes


    Blood group related antigens represent a group of carbohydrate determinants carried on both glycolipids and glycoproteins. They are usually mucin-type, and are detected on erythrocytes, certain epithelial cells, and in secretions of certain individuals. Sixteen genetically and biosynthetically distinct but inter-related specificities belong to this group of antigens, including A, B, H, Lewis a, Lewis b, Lewis x, Lewis y, and precursor type 1 chain antigens. This antibody belongs to the BG-7 group and detects the Lewis x (type 2 chain) blood-group antigen, which is expressed in gastrointestinal tumors, and lung cancers. It is found in crypt cells, which represent the proliferative compartment of the colonic mucosa, and strong homogeneous immunostaining is observed in most metastases and invasive cancer cells.

Answer

Thank you for your inquiry.

I can confirm that the storage temperature of our products can be found on the individual datasheets.

Short term storage is usually two weeks. If the products is not used within two weeks of purchase, we in general recommend to aliquot it and to store as stated for the long term storage. As a general rule, freeze/thaw cycle are to be avoided.

Please find below the long term storage conditions for the products you are interested in:

ab9100 : Upon delivery aliquot and store at -20°C. Avoid freeze / thaw cycles.

ab3358 : Store at +4°C.

ab3359 : Store at +4°C.

ab30667 : Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.

ab86128 : Aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.

Since the vials are small and we want the text to be readable, we strongly suggest to check the datasheets for the storage information. This will have the positive side effect that also all the other valuable information on the datasheet will be seen.

I hope this information is helpful and wish you a sunny day.

Question

Product code: 3358
Lot number: GR31367-2

Inquiry: Dear Abcam, I recently received an antibody against LeX from Abcam. Could you please tell me what the concentration of the antibody is? Reference number: ab3358 Lot number: GR31367-2 Kind regards,

Answer

Thank you for your enquiry.

I can confirm that ab3358Blood Group Lewis x antibody [P12] is sold as tissue culture supernatant. I have requested that the datasheetisupdated so thisinformation is clearer. Unpurified antibodies, such as those sold as whole antiserum, ascites or tissue culture supernatant will not have a concentration stated on the datasheet. Antibody concentration is usually determined by protein assay,and tissue culture supernatant will contain a lot of other proteins, which means the antibody quantification would not be accurate.

I can confirm that for this particular product, theconcentration is estimated at 10-50ug/ml.

I am sorry we are not able to provide an exact concentration on this occasion, but hope this information will be helpful to you. If you have any further questions, please do not hesitate to contact us.

Question

Was this antibody purified from ascites or tissue culture supernatant? What is the concentration?

Read More
Answer

Thank you for your enquiry. This antibody is tissue culture supernatant concentrated by ammonium sulfate precipitation. The concentration of our last lot was 180 ug/ml. We don't currently have any stock of this antibody, so the concentration may change with new stock. I hope this information helps. Please do not hesitate to contact us if you need anything further.
