Datasheet Extract

Asialo GM1 purified from Bovine brain tissue, methylated BSA and complete Freund's adjuvant.
Add. information Ig Classes of the antibody: IgG, IgA, and IgM.
Note: Since this antibody is not an antigen affinity purified product, the protein concentration is not equal to the concentration of Asialo-GM1-specific antibody, even after correcting for the Albumin content. Both the total protein and Albumin concentrations will vary from lot to lot.
Application Flow Cytometry.
Immunohistochemistry on Frozen Sections.
Immunohistochemistry on Paraffin Embedded Sections.
NK Cell Depletion.

Mouse - intravenously: 10-50 µl (approximately 20 µl; 50 injections can be made using 20 µl doses). The exact dosage should be decided from titration data (See "Protocols") and the nature of the study. The first injection may be effective for 4 days with a gradual diminution. Therefore, 3-4 injections are necessary for a 2 week study.
(Incubation) Days / Injection: 0 / 1st, 5 / 2nd, 10 / 3rd, 14 / 4th.
* 50 injections can be made using 20 μl doses.
Rat - intravenously: 50-250 µl (4 or 5 times the usual mouse dose is required). Health conditions and weight of rats should be taken into consideration. It is recommended that the researcher assay NK activity to determine the proper dosage.
Mouse and rat - intraperitoneally: Dosage should be equal to or greater than the i.v. dosage.
Background Gangliosides are neuraminic acid containing glycosphingolipids and represent characteristic constituents of the plasma membrane of eukaryotic cells. They are shed in the microenvironment and found as free components in plasma. In turn, free gangliosides are efficiently incorporated into the plasma cell membrane.
Concentration Antibody Titer: Approximately 1/1000 by Immunoflocculation test. Total Protein Concentration: 37 mg/ml. Albumin Concentration: 9 mg/ml.
Protocols Procedure For Measurement of Anti-NK Cell Activity
1. Preparation of target cells:
- Suspend 5 x 106 cells of YAC-1 in RPMI 1640 containing 10% FCS.
2. Preparation of effector cells:
- Inject 0.2 ml of polyinosinic- polycytidylic acid soduim salt solution (500 µg per ml of poly I:C in RPMI 1640) into BALB/c mice.
- Remove spleens from mice on the following day (after approximately 10 hours of treatment) and prepare spleen cell suspension as follows:
- Centrifuge at 1000 rpm for 10 minutes and discard supernatant.
- Add 0.83% NH4Cl to the tube to hemolyze the precipitated spleen cells.
- Centrifuge at 1000 rpm for 10 minutes and discard supernatant. Add 10 ml RPMI 1640 to wash cells.
Repeat washing process using same procedure.
- Adjust the cell number to 2.5 x 107 cells per ml.
3. Treatment of effector cells:
- Dilute the target cell suspension with RPMI 1640 to ratios of 1:50, 1:100, and 1:200.
- Place 0.5 ml of effector cell suspension into centrifugation tubes. Centrifuge at 1000 rpm for 10 minutes and discard supernatant.
- Add 0.5 ml of the diluted target cell suspension to each tube above and mix well.
- Incubate tubes at 37°C for 30 minutes in 5% CO2.
- Centrifuge at 1000 rpm for 10 minutes and discard supernatant.
- Prepare control by adding 0.5 ml of RPMI 1640 to effector cells. Mix well to make suspension.
- Make a dilution of Guinea Pig Complement with RPMI 1640 and add the diluted complement to effector cell suspensions. Mix well.
- Incubate at 37°C for 30 minutes with occasional stirring.
- Centrifuge at 1000 rpm for 10 minutes and discard supernatant.
- Add 1 ml of inactivated FCS (10% FCS in RPMI 1640) and mix well.
4. Measurement of activity (n=2):
- Place 100 µl of the target cell suspension into each well of microplate.
- Place 100 µl each of the untreated samples, the diluted samples, and the samples of effector cells with complement into each well.
For measurement of spontaneous Cr release, add 100 µl of RPMI 1640 containing inactivated 10% FCS to well.
- For measurement of maximum Cr release, centrifuge 0.5 ml of target cell suspension at 1000 rpm for 5 minutes. Discard supernatant and add 1.0 ml of sterile water.
- Cover the microplate and tubes. Incubate at 37°C for 10 hours in 5% CO2.
- Assay the radioactivity of 100 µl of each reaction mixture using an autogamma counter.
- Calculate the % Lysis using the following equation:
% Lysis =
Experimental Cr release - Spontaneous Cr release x 100
Maximum Cr release- Spontaneous Cr release

1. Preparation of target cells:
- Suspend 5 x 106 cells of YAC-1 in RPMI 1640 containing 10% FCS.
2. Preparation of effector cells:
Dilute the sample with RPMI 1640 to ratios of 1:2, 1:4, and 1:8
- Inject BALB/c mice with diluted samples in 0.2 ml doses (n=3).
- Dilute rabbit serum to 1:2 with RPMI 1640 and inject into BALB/c mice in 0.2 ml doses.
- After 3 days of treatment, remove spleens and prepare suspensions using RPMI 1640 as follows:
- Centrifuge at 1000 rpm for 10 minutes and discard supernatant.
- Add 0.83% NH4Cl to the tubes to hemolyze the precipitated spleen cells.
- Centrifuge at 1000 rpm for 10 minutes and discard supernatant.
- Add 10 ml of RPMI 1640 to the tubes to wash the precipitated cells. Repeat washing process using same procedure.
- Centrifuge at 1000 rpm for 10 minutes and collect the cells. Add RPMI 1640 containing inactivated 10% FCS to the tubes to adjust the cell number to 2.5 x 10e7 cells per ml.

Restore with 1 ml distilled water. Since the material is lyophilized with salts, use of other solvents such as PBS or MEM may increase the salt concentration.
Anti-Asialo GM1 polyclonal antibody reacts with Natural Killer (NK) cells.
It also exhibits slight reactivity with mouse monocytes (liver cells which contain no NK cells; bone marrow; fetal liver cells; spleen cells of nude mice), macrophages, and fetal thymocytes (12 days old; ratio of existence decreased gradually until there were none in newborn mice).
Anti-Asialo GM1 antiserum has been shown to eliminate NK activity in cells of various strains of mice and rats.
