HAT medium is used for the selection of hybrid cells in hybridoma technology. image credit . HYBRIDOMA TECHNOLOGY This technique includes the production of hybrid used by fusion of B lymphocytes with a myeloma cell. The hybrid cells thus produced have the ability to produce antibodies (due to B lymphocyte genome) and grow infinitely invitro( due to tumor cell genotype). Hybridoma cells are. Myeloma cells are immortalized cells that are cultured with 8-azaguanine to ensure their sensitivity to the hypoxanthine-aminopterin-thymidine (HAT) selection medium used after cell fusion. 1 A week before cell fusion, myeloma cells are grown in 8-azaguanine. Cells must have high viability and rapid growth. The HAT medium allows only the fused cells to survive in culture 11.  So in HAT medium, Cells not synthesized by De-novo synthesis due to presence of Aminopterin in HAT medium which blocks Di-hydro follate enzyme which is necessary for these synthesis.  For synthesis in salvage pathway it must requires HGPRT enzyme (Hypoxanthine Guanine Phospho-Ribosyl Transferase).  Where hypoxanthine and thymidine are used as precursors. 1

Hybridoma selection using HAT medium - Molecular Device

Thus, specific cell culture conditions (HAT media: Hypoxanthine, Aminopterin, Thymidine) + a myeloma partner with a HGPRT mutation enables the selection and survival of hybridomas (B cell:myeloma hybrids) vs. unfused myeloma cells or B cells. The key concept is that the hybridoma receives a functional HGPRT gene from the primary B cell, thus enabling the survival of hybridomas vs. myeloma. Therefore, the hybridoma cell only survives in HAT medium to isolate the specific antibody-producing cell using limited diluted method separate every individual cell through cloning the specific cell we obtain specific antibody they are identified using immune fluorescence method, their character was studied and stored separately. Uses of hybridoma cell. The pregnant detector using hybridoma. The resulting hybridomas are then cultured in tissue culture medium containing Hypoxathine, Aminopterin, Thymidine (HAT), a step which kills any unfused myeloma cells that might outgrow the other weaker hybridoma cells. Unfused B cells have limited powers of division and will die off naturally in culture. Ten days after the fusion process, culture supernatant is collected and tested for the. The hybridoma clones can be selected using HAT medium. Clones are screened and selected based on antigen specificity and immunoglobulin class. Each positive clone is confirmed, validated, and characterized (Isotyping). Positive clones are expanded, scaling up the production of the desired antibodies.

I think you are writing that this is happening with one animal and not all the animals you are recently harvesting cells from. Assuming this is the case, I think you got a bad mouse . You also mentioned that spleen cells from the animal initially produce antibody but then production stops even before fusion.

HAT medium - Wikipedi

Hybridoma cultures typically express a range of antibody concentrations from 1-50 μg/mL. Cultures are expanded in HAT medium with gradually increasing volumes to produce mg quantities for characterization studies. The final expanded cultures (100-200 mL) are allowed to grow to low viability to maximize the expression of antibodies. After. Using HAT selection, we: (i) genetically transformed HPRT- mutant cells to HPRT+ wild type by using DNA extracted from HPRT+ cells, and (ii) selected HPRT+ hybrid cells by fusing HPRT- D98/AH2 cells with skin cells. These approaches, which we dubbed in 1962 as a 'first step toward gene therapy', contributed to the later development of (i) cell fusion techniques, (ii) the development of.

CloneMedia Hybridoma Semi-Solid Selection and Cloning Medium (with HAT) is a semi-solid methylcellulose-based medium containing supplements to promote the growth of single-cell hybridomas into colonies in the presence of the selection agents hypoxanthine, aminopterin, and thymidine (HAT) as shown in Figure 3. CloneMedia's performance is comparative to Product X in terms of number of colonies. Since the advantages of FACS sorting (easy fusion of different hybrids) and HAT-medium selection (high selectivity) are combined the chance of isolating the wanted hybrid hybridomas will be much bet-ter, especially in cases when the fusion efficiency is very low.Fig. 2 .Fig. 3 .23Growth curve of HAT-sensitive anti-CEA hybridoma Dll-DG2 after seeding cells in 1 ml (1 × 104 cells/ml) into 24. HAT Hybridoma cells are selected using HAT (Hypoxanthine Aminopterin Thymidine) medium. HAT selection depends on the fact that mammalian cells can synthesize nucleotides by two different pathways: the de novo and the salvage pathways. Aminopterin (a folic acid analog) blocks the de novo pathway, while hypoxanthine and thymidine allow growth via the salvage pathway. Indeed, the DNA de novo.

The fusion mixture is then seeded into 96-well plates and the hybridomas are selected with hypoxanthine-aminopterin-thymidine (HAT) containing medium, which kills the unfused myeloma cells. Unfused B cells can't proliferate in vitro and finally die. Only the fused hybridoma cells can survive HAT selection and divide. Most commonly, supernatants from wells showing hybridoma growth are. Metabolic/biosynthetic enzymes - This strategy can be best explained by the HAT medium selection often used in hybridoma technology. HAT stands for hypoxanthine-aminopterin-thymidine: aminopterin blocks de-novo DNA synthesis and hypoxanthine and thymidine provide the raw materials for the alternative 'salvage pathway'. The key enzyme needed for the salvage pathway is HGPRT.
