B-lymphocyte antigen CD20 or CD20 is B lymphocyte cell-surface molecule. It is a 33-37 kDa non-glycosylated protein. CD20 is expressed on the surface of B-cells from the pre-B phase, the expression is lost in terminally differentiated plasma cells. [5] [6] CD20 is used as a therapeutical target of B-cell malignancies and autoimmune diseases. [6]
Ocrelizumab is a humanized monoclonal antibody that binds to a CD20 epitope that overlaps partially with the epitope to which rituximab binds. [10] It has an immunoglobulin G1 with a variable region against human CD20, with a human-mouse monoclonal 2H7 γ1-chain, bound via disulfide links with human-mouse monoclonal 2H7 κ-chain in a dimer.

On average, whole milk contains 3.25% fat—only a few percentage points higher than low-fat milk. To broaden your perspective, half-and-half can contain up to 18% fat, while heavy cream must be ...
A complete blood type would describe each of the 45 blood groups, and an individual's blood type is one of many possible combinations of blood-group antigens. [3] Almost always, an individual has the same blood group for life, but very rarely an individual's blood type changes through addition or suppression of an antigen in infection, malignancy, or autoimmune disease.
In breastfeeding women, low milk supply, also known as lactation insufficiency, insufficient milk syndrome, agalactia, agalactorrhea, hypogalactia or hypogalactorrhea, is the production of breast milk in daily volumes that do not fully meet the nutritional needs of her infant.
Milk is the first and only food infants receive during their first few months of life. However, if you've got several birthdays under your belt and somehow have an insatiable milk craving, you're ...
One is covered with an air-vent, the other(s) can be used to pump milk into the tank. A milk cooling tank usually stands on 4, 6, or 8 adjustable legs. The built-in tilt of the inner tank ensures that even the last drop of milk will eventually flow to the outlet. At the bottom, every milk cooling tank has a threaded outlet, usually including a ...
If you get two negative at-home COVID test results 48 hours apart after previously testing positive, you are likely no longer contagious. But how long that will take is "wholly dependent on the ...
