IHC-Positive Hybridoma Screening

Date: 2018-08-27 Author: Leading Biology Click: 415


Immunohistochemical (IHC) staining is widely used in the diagnosis of abnormal cells such as those found in cancerous tumors. Specific molecular markers are characteristic of particular cellular events such as proliferation or cell death (apoptosis). Immunohistochemistry is also widely used in basic research to understand the distribution and localization of biomarkers and differentially expressed proteins in different parts of a biological tissue. Immunohistochemistry (IHC) involves the process of selectively imaging antigens (proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues.

Based on molecular experimental professional team, Leading Biology established a complete set of services for IHC fidelity antibody preparation, after obtaining a large number of suspected positive hybridoma cells, we could verify the IHC availability antibodies for customers, and hand the purified hybridoma cell supernatant to customers for further validation test. One the one hand, it saves the customers' work and shorten the test cycle, on the other hand, it eliminates the false positive problem caused by the risk of sample transportation. At present, in addition to providing IHC validation services, we also face a vast number of scientific research and medical facilities, providing IHC experimental service. According to the customer's needs, we could complete the entire experimental service process from tissue embedding, slicing, staining, filming and analyzing.

Customer Provide

Protein antigen\plasmid\protein information + 20 antibody positive paraffin sections (3-5μm)


1. Antigen preparation\Plasmid expression\Protein purification\Peptide design, synthesis and conjugation.

2. Immunization of 5-6 Balb/c mice.

3. ELISA/Western-blot test to monitor the antibody titer and specificity in mice serum, according to ELISA and WB test result, screening mice.

4. Cell fusion: fusing with the myeloma cells SP2/0.

5. Positive screening: Using ELISA test to screening the antibody positive hybridoma clone.

6. Subclone: Using limited dilution to produce subclone from positive clone. According to customers’ requirements, we also could screen out the monoclonal cell line which could produce Ig antibodies firmly (extra charge).

7. 3 positive cell clones were screened out by using IHC, and the purified supernatants of cell cultures were sent to customers for test.

8. Ascites preparation: Using mice celiac inoculation to produce the ascites of hybridoma products.

9. Antibody purification: Purify the secretory antibodies from 2 monoclonal hybridoma cell lines.


(each antigen, 5 mice)

1. 5mg polypeptide

2. 2 immunogen specific monoclonal hybridoma cell lines.

3. Each cell line provide 10ml (1mg/ml) purified antibody, ELISA  titer was above 1:50,000.WB test positive.

4. If customer requires, we could provide: prepared ascites (titer 1:500-1000, extra charge), hybridoma cell culture supernatant (for WB test).

5. Complete lab report, remaining antigens.
