  • Mesh - can pass water and air through 100%

Impermeable Membranes:

  • Clay - permeability rate is extremely low, and water cannot pass through
  • Ziplock bag - nothing can come in or out

Semipermeable Membranes:

  • Plant and Animal cell membranes (lipid bilayer) - only certain substances can pass through, like soluble vitamins
  • Cell Organelle Membranes - only certain substances can pass through the mitochondria, for example

Hybridoma cells resulting from the fusion of B lymphocytes and myeloma cells produce specific monoclonal antibodies. Hybridomas are generated by fusing spleen cells (plasma cells) from immunized hosts with a compatible myeloma cell line (malignant and immortal plasma cell line).

<h3>What is hybridomas?</h3>
  • A hybriddoma is a culture of hybrid cells formed by the fusion of B and myeloma cells. Hybridoma technology gives rise to hybridomas.
  • This technique was created to create mAbs. Hybridomas have two crucial B cell properties: antibody production and myeloma cell immortalization.
  • Hybridoma technology ushered in a paradigm change by enabling the mass manufacture of extremely specific and sensitive monoclonal antibodies.
  • The mAbs have been widely employed in diagnostics, including the detection of cancer. These are also widely utilized in cancer treatment.
