ELISA Kits
Enzyme linked immunosorbent assay (ELISA) is a common laboratory technique used to detect the presence of an analyte in a sample solution. Novatein Biosciences offers a rich portfolio of ELISA kits covering several research areas (cancer, diabetes, obesity, hormones, food, cytokines etc) and multiple species (Human, Mouse, Rat, Dog, Pig, Chicken, Rabbit, Bovine).

We offer ELISA kits in two formats:

Primary Antibodies

As a leading manufacturer and distributor of antibodies, NovateinBio is committed to providing the antibody you need for research with the quality you deserved. All of our antibodies are tested on WB, ELISA or IHC over a number of tissues and cell lysates, as well as recombinant proteins. NovateinBio guarantees that all the antibodies perform as described on the datasheet.

To search an antibody, just use the search box to search our antibody database. If you can't find the antibody, it doesn't mean we don't have it. Just email us the name or type of the antibody and we will locate the antibody for you. We have some antibodies labeled with biotin, HRP, FITC or other compounds. If you need customer conjugation, please contact us. Our name and reputation stand behind every antibody we make or distribute. If you have any question regarding our antibodies, please let us know.

Customers have the flexibility of choosing the detection antibody conjugation type. All our Antibody Pairs are validated using any of the above applications.
2019-nCov/COVID-19

The outbreak of a novel betacoronavirus (SARS-CoV-2/2019-nCov) is a pandemic that resulted in almost 5 million lives loss by October, 2021. The CoV spike (S) glycoprotein is a key target for urgently needed vaccines, therapeutic antibodies, and diagnostics. So far, S1 protein mRNA vaccine and protein vaccine have been used by several billions of people.

2019-nCoV/COVID-19/SARS-CoV2 makes use of a densely glycosylated, homotrimeric class I fusion spike (S) protein to gain entry into host cells. The S protein exists in a metastable prefusion conformation that undergoes a dramatic structural rearrangement to fuse the viral membrane with the host cell membrane. This process is triggered by binding of the S1 subunit to a host-cell receptor ACE2, which destabilizes the prefusion trimer, resulting in shedding of the S1 subunit and transition of the S2 subunit to a highly stable postfusion conformation. In order to engage a host-cell receptor, the receptor-binding domain (RBD) of S1 undergoes hinge-like conformational movements that transiently hide or expose the determinants of receptor binding. These two states are referred to as the “down” conformation and the “up” conformation, where “down” corresponds to the receptor-inaccessible state and “up” corresponds to the receptor-accessible state, which is thought to be less stable.

Fluorescent...

Fluorescent immunoassay ( FIA ) or Fluorophore linked immunosorbent assay (FLISA) has multiple advantages over the tranditional ELISA ( enzyme linked immunosorbent assay):

•   Few steps and shorter assay time

•   Wider linearity range

•   Multiplex saves more hands-on time

•   Multiplex saves samples

•   Multiplex makes normalization simpler and  more accurate.
Monkeypox...

Monkeypox is an infectious viral disease that can occur in humans and some other animals. Symptoms include fever, swollen lymph nodes, and a rash that forms blisters and then crusts over. The time from exposure to onset of symptoms ranges from five to twenty-one days. The duration of symptoms is typically two to four weeks. There may be mild symptoms, and it may occur without any symptoms being known. The classic presentation of fever and muscle pains, followed by swollen glands, with lesions all at the same stage, has not been found to be common to all outbreaks. Cases may be severe, especially in children, pregnant women or people with suppressed immune systems.

Clinical differential diagnosis must consider other rash illnesses, such as chickenpox, measles, bacterial skin infections, scabies, syphilis and medication-associated allergies. Lymphadenopathy during the prodromal stage of illness can distinguish monkeypox from chickenpox or smallpox. Diagnosis can be verified by testing for the virus.

Smallpox vaccine has been reported to reduce the risk of monkeypox among previously vaccinated persons in Africa. The decrease in immunity to poxviruses in exposed populations is a factor in the prevalence of monkeypox. It is attributed to waning cross-protective immunity among those vaccinated before 1980, when mass smallpox vaccinations were discontinued, and to the gradually increasing proportion of unvaccinated individuals.
