Purpose of antibody wash It is common practice after surface staining cells for flow cytometry analysis to wash the antibody out of solution before analyzing a sample. I have tried analysis with and without washing th...
Two reasons for antibody wash: 1. To limit non-specific epitope binding. All ABs have specificity. excess AB that is not bound, if also pre-conjugated to a fluorophore, may allow for excitation of the fluorophore while going through flow even though the antibody

Neutralizing antibody - Wikipedia
A neutralizing antibody (NAb) is an antibody that defends a cell from a pathogen or infectious particle by neutralizing any effect it has biologically. Neutralization renders the particle no longer infectious or pathogenic. Neutralizing antibodies are part of the humoral response of the adaptive immune system against viruses, intracellular bacteria and microbial toxin.

Please explain how to test antibody specificity
antibodies from origin technologies the search for ultra specific application validated antibodies is over origin provides a unique solution to evaluate antibody microarray represents a unique recombinant human protein antibodies are tested on this array and signals of interaction are analyzed to determine if the antibody

How is antibody production stopped? Once clonal selection is done, B cells would start dividing and producing antibodies. So, after an antigen is eliminated, what stops the division of B cells and antibody production?
Antibodies have to be produced as antibody mediated immune mechanisms are extremely important for memory and the reason why a subsequent infection is cleared

What antibody targets are being tested for in the publicly offered UK antibody test? In late August 2021 the NHS (UK) offered people who test positive for COVID what is referred to in this BBC report as a _“new antibo...
Antibody tests have only been used on people involved in studies or surveys. This action is what they are referring to as “new” here, not the antibody test itself.

Custom Rabbit Polyclonal Antibody Production Protocols
90-day rabbit immunization protocol. Of the three standard options for rabbit polyclonal antibody production, this protocol is optimized to maximize speed, titer, and volume for a competitive price. Originally developed and adopted by the NIH, this procedure meets the minimum requirements mandated by most pharmaceutical companies.

Antibody production in secondary immune response Can IgG antibodies be produced in the secondary immune response without the help of T cells? Is the affinity of antibody for antigens higher during secondary immune re...
1) The secondary response requires CD4+ T cells to activate memory B cells. That first paper actually gives some evidence that some of the rapidity could arise because T cells and memory B cells are in very close proximity to each other in germinal centers. 2) Yes. The affinity of antibodies increas...

How do the variable portions of antibody genes look in cells which don't produce antibodies? There are several families of antibodies found in mammals. They may have two or more antibody domains which contain heavy an...
Perhaps you want to ask how VDJ recombination is regulated in non lymphoid cells.. Well even in immature lymphoid cells VDJ recombination is regulated. And also Ig genes are suppressed in T-cell and TCR genes are suppressed in B-cells.. Also, the recombination of Ig is suppressed in T-cell and vice-...

Will a polyclonal antibody attach to proteins of different kDA? If I have a GST 26kDa polyclonal antibody, will it bind to the GST 28kDa protein as well?
If the sequence of the 26 kDa form is included within the sequence of the 28 kDa form then the answer is 'probably yes'. However if the N- or C-terminus of the short form is an important/dominant epitope and it is masked in the long form (by being extended) then the activity of the serum against the...

Conjugate secondary antibody Why is the secondary antibody conjugated to the enzyme in ELISA, instead of the primary antibody? Wouldn't it be easier to conjugate the enzyme to the primary antibody?
Making an antibody-enzyme conjugate isn't trivial.

How can antibodies in rapid antibody tests be kept at room temperature without denaturing? The normal temperature for long term antibody storage is around -20 degrees Celsius. However, when developed into rapid antibo...
Antibodies have no problem with room temperature. Naturally, antibodies expect to survive for many days or weeks at body temperature, which is much higher than room temperature (at least, mine is). -20°C is recommended for very long-term storage (many months or years) of antibodies, but they are typ...
